After just a few uses we developed a hole in the bottom. Core was gracious to send some patch material. When we went to apply the patch, we discovered many small holes in the floor. (We always lay down a heavy tarp first and often line the inside with rubber puzzle mat material for comfort). When I lay under the assembled tent to look for more holes, it was like looking at a starry sky on a dark night - dozens of small holes. In the rain we ended up with the bottom of our sleeping pads wet. Core offered more patch material which is great. Just disappointed in the quality of the floor. But still use it as setup is nice. Space is nice. Especially for one adult in one or two kids plus gear.
