Let me start by saying this ab roller is NO JOKE. After just two days of using it, my abs were screaming for mercy - in that satisfying 'good workout' way. The automatic rebound feature is a game-changer, especially when you're exhausted and need that extra help rolling back up.

The dual-wheel design makes balancing surprisingly easy compared to single-wheel rollers I've tried. I can actually focus on my form without worrying about tipping sideways mid-roll. The included knee pad? Lifesaver. Though I agree with other reviewers that it's a bit thin - I sometimes double it up with a yoga mat for extra cushion.

Now for the not-so-great parts: The phone holder feels like an afterthought. It works, but I'm too busy trying not to collapse to watch videos anyway. And those handles? They pop off if you look at them wrong. I've learned to just leave it assembled in my workout corner.

Where this roller really shines is in those slow, controlled rolls where you can really feel every muscle in your core engage. That rebound action gives just enough assistance to push through one more rep when your abs are burning.

Would I recommend it? Yes, but with caveats. It's fantastic for serious core work, but if you're constantly moving equipment around or expecting premium build quality throughout, you might be disappointed. For the price though, it delivers where it counts - giving your abs an insane workout.
