This is my second ClearFlex. The material is the reason I came back—it stretches evenly and never tugs. I’m giving four stars because the new one is a little cloudier than my first, not as crystal clear as the listing photos, though it works the same.

For the price I was skeptical, but the stretch on this thing is no joke.

I wanted to like this more than I did. The clear gel body is genuinely stretchy and it folds flat into my overnight bag, which is a plus, and it didn’t have any weird smell out of the box. That said, for $199 I expected more than a disposable trainer—mine started showing small nicks around the base after the third week even with gentle hand washing and air drying. It still works, but I don’t see it lasting another month. I’d probably rebuy only if they made a reusable version.

Ordered on a Monday and it was at my door by Wednesday in plain packaging, which I appreciated. The trainer itself is much stretchier than I expected from the photos, and it has a nice, solid feel despite being flexible.

Not gonna lie, the first few tries felt a little awkward—the shape is wider than what I’m used to. After about a week I found the angle that works, and now it’s part of my Sunday wind-down. Knocking one star for that learning curve.

Bought this for my wife after she mentioned wanting something low-pressure for her solo time. She was hesitant at first because it looks almost too simple, but after the second week she told me it’s become her favorite part of a long bath. I can’t speak to the feel myself, but from an outside view it arrived fast, the packaging was neutral, and she says the transparent material is easy to see when it’s fully clean. Happy I took the chance.
