I researched bouncy castles quite a bit as it's a big I investment. I saw a nice commercial one but realized that at 200lbs I would end up hating when my kids asked me for it. These residential units are really a great/fair balance between durable but still light enough to throw over your shoulder and bring inside for storage. Feels about 50-60 lbs. It's pretty easy to roll up but it's best to give yourself plenty of time to let it dry as you go. The blower is very well powered and certainly quieter than your kids. I would say the only thing they should improve are the plastic stakes which I'm expecting will break soon (although the ones to hold the blower are a better design - maybe only this style would be a good choice). Other things for parents to consider : I chose the sports model not just because my kids were excited about the soccer section but a) the slide has nice tall sides (like the shark, unlike the pirate). And especially b) no bouncy section. I know this seems like a loss, but if you've ever had kids on a bouncy jumper you know that 100% of the time a kid(s) gets hurt. We've had this up 3 times with kids from 4-8 and we are injury and crying free. There's also PLENTY of space (we had 7 at once no problem). All in all an excellent unit, I hope I can keep in good shape for a few years. Also, great price and very good delivery exactly on time, no problems.
