A fun challenge!

Our son has played with K'nex before, but this was the first building set that he tried. Building it kept him creatively entertained for several hours and he he thoroughly loved the challenge of figuring out how to put it together. The end result of a coaster that is over 2 1/2 feet high, totally wowed him. I can't tell you how often I've found him standing there in front of the completed coaster, watching the little motorized car zoom around- it's crazy fast! His 2 younger sisters have been fascinated too. Our son did find the directions a bit hard to understand at a few places and needed a little help, but it wasn't a big deal and we soon had them figured out. I'm guessing if a child is familiar with K'nex sets, it wouldn't be a problem though. We can't wait to download the instructions for a 2nd coaster on knex.com! I received this product for free in exchange for my honest review. The little coaster car requires 2 AA batteries, which aren't included, so make sure you have some on hand.

Great Family Activity

When the K'NEX Wild Whiplash Coaster arrived on my porch, both of my kids (ages 7 and 11) claimed it as their own. After some mediating, we all decided we would put it together as a family. My 7 year old would find all the appropriate pieces for the current page of instructions, and my 11 year old daughter and I would work together to get it put together. We had a great time working together, and it was actually quite easy to follow. My one complaint is that sometimes the picture wasn't completely clear which direction the connector piece was supposed to be facing. I had to turn a couple of them a different direction after adding more components onto that part, when it was discovered there wasn't a space to place them. It was really easy to get them switched around, and was clear which direction it should be facing at that point. The pieces fit together very nicely, and for such small pieces I was surprised by how sturdy they were. I was able to easily pick up the entire thing and move it to a different location without anything coming apart. Once the entire track was put together we turned the motor on and watched it go. I have to say, it's quite mesmerizing to watch. The roller coaster car slides down the track with such speed and ease, and then watching it climb is fun too. My daughter actually discovered that she could push the car from the bottom and it would speed up to the top of the hill. She spent a long time sliding it all the way up and watching it quickly come down. We also tried to attach one of their toys to the car, so the toy could take a ride on the roller coaster. It messed with the aerodynamics too much, and it didn't end up making it all the way down the track. I really loved that the toy taught some really awesome engineering concepts, and even taught about gravity and aerodynamics (since the toy experiment failed). All in all, we really enjoyed spending some down time together, without screens in front of our faces! I was given the K'NEX Whiplash Roller Coaster free of charge in exchange for my honest review of the toy.

Great Toy for Older Kids

My son has always loved K'Nex and building fun projects since he was younger. Now that he's a teenager, some of them seem to be made for only little kids. This new K'NEX Wild Whiplash Coaster Building Set was perfect for him. It had smaller pieces and the directions were easy to follow, but still challenging. If you have itty bitty's, be careful of having an older child use these small pieces near them. My son said that he loved building it, and was so proud of seeing the coaster work when he was finished (and enjoyed some soda). He said that he wants to use it as a decoration in his toy room now and play with it while he's working on his computer, etc. I would definitely recommend for the holidays!! I received this product for free in exchange for my honest review.

Perfect Gift For Tweens

My boys loved this! We have owned K'Nex before but this is our first kit. My boys are are (6, 10, 16) my 6 year old mostly sat and watched during the building process but my 10 year old was able to put it together with no problems at all. My 16 year old loved it as well but would probably not admit it. This product has fourteen feet worth of track and has a motorized chain-lift! It is totally like the real thing in miniature and you can dress it up with decals and stickers. Even though this is a toy, the truth is the coaster is pretty realistic and takes about 2-3 hours to build. With 580 parts and standing more than two feet tall, this roller coaster is no joke. Best of all, when you finish building it you can send your roller car riding! The instructions were very easy to follow and understand. The boys are now excited to experiment with their own design. If you have a roller coaster enthusiast, potential architect or general lover of motorized toys in the family or on your list, this should be a home run to say the least. I give this awesome K'Nex building set five solid stars out of five. I received this product for free in exchange for my honest review.

Kids will be amazed at what they can build!

In exchange for my honest review, I was provided this product for free. My kids absolutely loved this set! They quickly built the coaster featured on the outside of the box within an hour. They showed me and I was amazed at how big it came out to be. Once the motor was turned on the coaster begin to move! I really was impressed at their construction skills. They then showed me several different builds, all featuring the motor pulling the cart through loops and so many other cool designs. We have had K'nex sets in the past but these snapped together much easier. I loved how the set kept them busy for hours.

Whiplash Coaster Fun!

My 10 year old son was very excited to receive the K'NEX Wild Whiplash Coaster Building Set in the mail. As soon as he got the package out of the box he immediately opened it. (I was surprised how small the box was because the finished Coaster measures just under 3 feet wide and 3 feet wide). In the box was a large, colorful instruction book, a set of graphic panels, a motor, a coaster and 2 plastic bags full of pieces. My son carefully separated all the pieces and parts by type and color before beginning building. I was impressed that he put the entire Coaster together all by himself without needing any assistance or asking me any questions. He loves science, building, and figuring out how things work so this was a great set for him. Since putting the Coaster together he has been happily playing with it, as has my 7 year old daughter. I think this set is great for a boy or girl who enjoys putting things together or building sets. I also liked that this set could be built by a non-reader, or a child who is not a strong reader, because the instruction booklet is filled with big colorful pictures instead of words. Lastly, I thought that at the end of the booklet the tips and troubleshooting suggestions was a good addition for kids and parents having difficulty building the set. K'NEX even threw in a 1-800 number for assistance which I thought was superb. Although we received this K'NEX for free in exchange for our review, I would purchase products from this company again in the future.

Takes Quite a Long Time, But Worth It!

So first off, there are a LOT of teeny tiny little pieces to keep track of, so this is pretty age-sensitive. I suggest you get small bins or bowls to sort them out before attempting to build it, as they come all jumbled up in one bag, and you don't want to have to dig through it. You'll want something to put them in, because they will roll all over the place if not contained. This is not something that you can just whip together fast. It probably depends on skills, but to give you an idea, it was my first time at putting together something like this, and it took me a good six hours to do it by myself. One thing that can be time consuming is that some of the illustrations don't show the position of some of the parts clearly, so some experimentation is needed. I also found that I didn't need all the links to the chain, as it was too long if I used them all. And yes, you have to put the chain links together. Like I said, it takes a while. Once you're done, it's a pretty entertaining toy. The chain drive will push the car down or back up, and send it through the many loops. I did a couple of test runs and did have to adjust the position of some of the parts, but in the end, it was a smooth movement throughout. Not to mention, it looks seriously cool. One thing to remember...this is a bunch of little plastic widgets and whatnots, so it's not going to take a lot of abuse. I didn't have a problem with normal play, though. This set is almost like two toys in one, because you get the fun of building it, plus the finished coaster. Very fun to play with, too. I received a free product for review purposes. My opinions and lack of building ability are my own.

Our first K'NEX build was a hit!

Building our K'NEX coaster was a family affair! The kids sorted all the pieces, counting them out to make sure they were all there for each step. (Great math practice!) Each picture instruction made it a fun "puzzle" to put together. I knew the coaster would be big based on the dimensions, but it was different seeing it all put together and running. It's an impressive sight for the price! This is the first of many K'NEX products for us! I received this product for free in exchange for my honest review.

Fun Coaster, Great Value, Finicky Setup

We received the K'NEX Wild Whiplash Coaster Building Set for free for review purposes. This isn't our first K'NEX Coaster, so we immediately started by sorting the pieces into small bins. It takes some time upfront, but makes it a lot easier to find what you're looking for at each step. We found the directions to be mostly clear. My 9-year old daughter and 11-year old son were able to do a lot of the steps with minimal help. There are a few spots where it's not entirely clear how to orient a piece, but it all worked out in the end. We spent about 2-3 hours assembling it. It would probably take an adult less time, but if a family is doing it together, expect to fall at the higher end of that range. We had a combo of family build and adult-only build, but with a lot of stopping and starting and distractions along the way. Once built, we had some difficulty with the car not making it around the second loop. We fiddled with it and fiddled with it until we got it to work. We actually had to slightly bend the wheels on the car to get it to run more smoothly, but after that we had no problems whatsoever. One of the nice benefits of this set is that it has alternative build instructions so once you get tired of this setup, you can build the other one. The Wild Whiplash Coaster requires two AA batteries that aren't included so do plan ahead (I'd buy extras to have on hand as well). Overall, we are happy with the coaster and think it's a good value for the price.

Fun & Challenging Toy

My son is 10 years old and this was our 1st K'nex product. We were excited to build it together because the idea of a roller coaster over 2 feet in your bedroom is always a great idea! I was a bit apprehensive at first seeing how small the pieces were & how many. I will admit it was challenging since we have never put a K'nex product together before. So I would suggest getting familiar with the pieces first & separating them into groups. The directions were easy to follow but some of the pictures were a bit confusing on how the pieces should fit into each other. We figured it out. With some breaks in between it took us over 3 hours to build. Once we completed it, I'm glad we had an area in his bedroom that would fit. It is high & you do want it to last for a few days. It was fun to see the car zip up, down & loop through. My youngest nephew had the most fun with it even though he almost crashed it down a couple of times! This is a great holiday gift for the family because you will get some bonding time together and a break from electronics! Well worth the price! I was given the K'NEX Whiplash Roller Coaster free of charge in exchange for my honest review of the toy.
