Santa brought this for Christmas. My daughter does acrobatic gymnastics and wanted an air track to practice at home. I did a lot of research and there are a variety of mats (and prices) out there. I was worried about the quality of the product given that it was less expensive that others I looked at but we are 4.5 months in and it seems to perform as expected. This is the largest one that would fit in our garage (our garage has high ceilings – about 10 ft). It is easy to inflate but kind of a pain to deflate so we keep it inflated and just stack it up against the side garage wall when not in use. We haven’t had to add air yet so it seems to hold air well. It takes two adults to move it. It is only used and stored indoors.
