I purchased the 13.12ft x 3.28ft x .33ft airtrack. It fits three short backhand-springs. It can also fit a round-off backhand-spring, starting the round-off on the beginning of the airtrack. The only (minor) issue we had was when blowing up the airtrack. The pump was letting a small amount of air out when I was blowing it up. I layered tape around the pump (the part that inserts into the airtrack) to get it to the right fit, that way air could not escape when blowing it up. After doing this, there were no problems and the airtrack blew up better. The first time blowing up the airtrack, I did not blow it up enough, and when I jumped on it hard, my feet touched the ground. The next time I blew it up, the way I knew it was finished was when the corners were firm when I pressed down on them. I brought it in the pool and there were no problems. The top side arrived a little bit dirty but after the pool, the stains were gone. There is NO “AKSPORT” logo on either side as shown in the pictures. There were also only directions to blow up the airtrack, not directions on where you can and where you cannot play on the airtrack. Other than the minor issues, this is a great airtrack for the price.Practicing cheerleading skills!This is all my daughter has been talking about. She finally got it as a surprise and now she won't quit flipping. Perfect for an 11yr old with hopes of being the next Simone6 BileLove this product my kids were so excited to use it. It feels and works amazing for a tumbling floor at home only draw back is that the the second you remove the air pump till you place the plug air blows back bbn out of it quite quickly.I love this so much!!! It is really helping me improve with jumps, my backhand spring and helping me with my standing tuck. I was confused of how to inflate it at first but a 1 minute youtube video really did the trick lol and it is super easy! I love this soo much and can’t wait to improve more!!!My grand daughter loves it!!! 20' Length perfect for long distance 'cheer' flips. Easy to assemble. Had a difficult time with USPS PRIME delivery. 1st attempt was lost in transit. 2nd order was finally delivered, but 1 week late. Grand daughter says it was worth the wait.Harder than I though at first. Definitely worth it for my daughter. Great quality. Easy to put together.Great quality for priceGood value , my granddaughter loves it for practising her gymnasticsI was excited to find this mat with no shipping fees. Being on sale, I scooped it up for my little cheerleader to practice her tumbling. The included pump inflates the mat within a minute or two. We also used it to deflate the mat. We were even able to fold it back up to fit in the provides bag. We ordered the 10' mat the is 4" tall. 9 year old daughter finds it a good combination of squish and support and gives her the confidence to practice at home what she would only do at the gym previously. If you have space, recommend purchasing as big as able. Does weigh more than the suggested 3lbs.I ordered this mat for my daughter and was very disappointed to find it wouldn’t hold air. I made note of it and was contacted within a couple days by their service rep Anna. They did everything they could to rectify the situation, explaining what most likely happened to the mat and then replaced it at no extra cost.I am very satisfied with the product and the level of care this seller takes to ensure customer satisfaction. I will be purchasing from them again.This product is awesome! My daughter loves this gymnastic mat she uses it everyday. Why spend all this money when you can get something for less for the same thing. I would definitely order this again and recommend this to anyone.My daughter love this airtrack. She has been learning tumbling and cheerleading before covid19 isolation started. With this airtrack at home, she can practice at home and improve her skills. The airtrack come with an electric pump that pumps very fast (it's so fast that I was afraid it would over pump). The quality of the airtrack feel tough and durable. The one we have is 10 feet long, it fit inside our small basement and still have a bit of a room. I would recommend it if you don't mind spend 279CAD. That was the lowest price I could find out there.
