Wasn't sure about the inflatable part at first, but being able to start small and slowly add air until it's just right honestly changed the whole experience for me. The release valve lets it deflate gradually instead of all at once, which I appreciated.

The pump gives decent control over the size, and I like that I can stop exactly where it feels right instead of guessing. Takes a bit of patience to inflate slowly, but the adjustable fit is worth it.

The pump lets you fine-tune the inflation in small increments, which is way better than guessing with fixed sizes. Took me a couple tries to get the valve seated right so it holds air perfectly, but after that it's been solid.
