I was more excited about this tent than my kids and it didn't disappoint! The design is absolutely perfect - it allows kids (my 6 and 3.5) to have enough space inside the tent to lie down or stand up, the mesh sides make it breathable and the roof keeps balls inside. I have about 800 balls in it and that's a lot! I wasn't expecting much from such a cheap tent but the construction and stitching looks sturdy and so far my kids haven't been able to bend the sides while playing. Note that I tweaked the large flap a bit by sewing thick elastics with a small hole so the button I sewed to the tent could go through the loop to prevent balls from escaping tent flow, and it worked great! One of the best surprises for my kids! Thank you!
