Awesome, although it took me a little faith to inflate it because it was huge (of course, I was inflating it with a regular pump), it is absolutely ideal!!! I highly recommend it!!!

I don't know if I was unlucky, but the specific one I bought had a hole and was losing air. I bought a patch and fixed it, and since then everything is okay. It has 2 caps so you can deflate it immediately if you want. I hope it was an isolated incident
