Wow! Seriously, wow. This spa is a high quality product. It took about 20 minutes getting it ready to fill. It took a total of 30 minutes to fill, and we have terrible water pressure. Within 20 minutes of turning on the heating unit it was notably warmer. The controls are easy to use and the pump set up is clearly labeled and ready to hook-up. The only thing I had trouble with at all was spreading the pool out after removing it from the box but that is because the material is heavy duty. It didn't matter anyway, once I connected the pump and started filling the body with air. It filled no problem in minutes. I am still impressed with the fortitude of this material. I decided to set the tub up on my patio slab. There is a pillar behind the tub and when I wasn't paying attention the tub pushed into a small thin wire that protrudes through the stucco. This would have been a big problem in a lesser tub. The very sharp piece of metal mesh did not penetrate at all. I am over 200 lbs and can sit on the walls no problem. I am also in love with the connections to the pump/heater. There wasn't a single drop of water leaked and hasn't been since. I sincerely wish that Coleman made an above ground pool. With this simple, effective design you really can't go wrong. I didn't need a single tool or to rig anything to make it work right. I'm impressed. There is a drainage tube off the pump side of the tub. Make sure that before you fill it with water it is near wherever you'd like to drain. I don't know the weight with water or people but you do need two people to move the box if it's full. Once you unpack it though the pieces are manageable. Now, I live in Arizona so the coolest it gets here at night is about 35F. If you live in a cooler climate consider putting this indoors. It took about 9 hours for this to warm from 86 degrees to 104 degrees. Not bad if you ask me. However, if it were colder it would be more work and take considerably longer. Make sure to put the bubble pad underneath to insulate from the ground. The maker suggests changing the water weekly or more depending on use. They also recommend changing the filter cartridges weekly depending on use. You need to do this and they aren't free. Consider the overall cost if you want to use this regularly. The filters cost between $10 and $14 dollars apiece from what I can find. Countering any possible negative you can find here is the simple fact that this tub comes with you wherever you go. Indoor, outdoor, rental or property owner this thing IS going to meet the need. Also you can comfortably sit 4 200 lb. adults in here.
