We purchased this for our 1 year old and 4 year old and they LOVE it! We actually use ours inside. It's great to have something for them to get some energy out in these cold winter months! Our friends think it's a great idea and may have started a new trend! The quality of this bounce house is amazing! My husband and I can sit in there with the kids and watch them jump! It has been fun for the whole family! The only thing I'd change (if I had to pick something) is the make the blower more quiet. I would recommend this product to anyone looking to have fun and wear their kids out in the process!
