Rated 4 out of 5 Good Product With Modification Well, to start, I have owned this product for over a year and interact with it daily.So, we will start with the con of this product. The top "wheel" does not spin properly and makes a ton of noise when it is trying to be used. Not to fear, stick a sock under the wheel and the noise stops. New problem forms, now it is a hidey hole for our little friend, meaning yes, there is a potty problem, but this is going to occur no matter where they choose to nest and so it is really not that big of a deal.And now for the pros!!! The top viewing area. What a great spot to have treat time or to handle your little friend. Not a fan of trying to pick them up? No problem, try holding your hand next to the "slide" and let your pet walk into your hand at their own pace. Access to the cage is wonderful, there is a door at the front, not the top, so it is easier to train your pet that you are not there to harm them. And the food dish is the perfect size and can be placed anywhere, unlike a lot of the small corner dishes. The water bottle is conveniently placed so that your pet can access it, you can fill it, and it is not in the way of anything. There are wonderful connections.I personally have a wonderful little female winter white (dwarf) hamster who is active, so I have added a lot of tubes, and the cage is sturdy and can handle it. I also added an internal small wheel to the cage, and there is still plenty of room to place treats and additional furniture in the cage.In conclusion... Poor wheel design on top that can be modified with a sock, but absolutely FANTASTIC design to the rest of the cage!!! 11/08/2010
Rated 1 out of 5 by Me1985 Good Intentions, Horrible Design My sons have a hamster in this habit. The wheel on top and the small compartment are a horrible design flaw in this cage. First, the shedding that small critters naturally move around is slung constantly out of the wheel due to small gaps between the molded plastic. The other small compartment on top is nothing more than a giant toilet to all animals, which has no ventilation to make the smell even better. Save your money and buy anything but this waste of money unless you enjoy sweeping up the shedding on a daily bases. 07/10/2010
Rated 4 out of 5 by LittleM4 Pretty Good This hamster cage is really good there is only one bad thing tht I HATE! the hamsters use the top compartment as a potty and it smells soo bad cuz there is no vents beside the side tube but it barely works .... but it is good overall besides that one issue 09/08/2010
Rated 1 out of 5 by DoNotBuyCage Do NOT Waste Your Money Or Time On This Product! I do not recommend purchasing the Super Pet CritterTrail Extreme Challenge Habitat. Do not waste your money. I received the cage and put it all together as the instructions told me to. I had my husband check my work to make sure everything was secure. We placed our two mice in the cage and about 3 days went by before I realized the water bottle was not functioning properly. It was vacuum sealed so tight the mice could not get any water. So I fixed that problem by placing a different water bottle in the cage. About another week went by and we realized both mice had escaped the cage. We searched the cage for a hole, damage, a gap...ANYTHING that would explain why the pets were missing. The cage was completely intact and we could not figure out how they got out. I was able to find one of the mice and placed him back in the cage. He was fine for about another week to a week and a half before he escaped again. Upon the next cage inspection again everything is intact, no holes, no gaps...I CANNOT FIGURE OUT HOW THEY GOT OUT. But now I am out the money for their food, I am out money for the cage, I am out money for the replacement water bottle and HAVE NO PET MICE. Do not buy this cage. My mice were perfectly fine for a month in a glass aquarium. I wish I would have left them in the aquarium. 10/19/2011
