Let me start by saying this little machine packs a punch! As someone who's 5'7" and 160lbs, I was skeptical about its sturdiness at first, but the steel frame holds up beautifully - no wobbling even during intense sessions.

The assembly was laughably easy. I had it ready in under 10 minutes while watching TV (the instructions could be better translated though). The foldable design is genius - it tucks neatly behind my bedroom door, making it perfect for my tiny apartment.

What surprised me most was the versatility. While marketed as an ab trainer, I've discovered killer workouts for my arms and glutes too. The adjustable resistance (I'm currently on level 3) provides noticeable progression - my core strength has improved significantly in just three weeks.

The LCD counter keeps me motivated, though resetting it requires some button-mashing trial and error. The knee pads did loosen after two weeks (annoying squeaks!), but a quick tighten with the included tools fixed it.

At this price point, I wasn't expecting miracles, but the burn I feel after 15 minutes proves its effectiveness. It's become my go-to for quick morning workouts before work. Just be warned - if you're over 200lbs like one of my friends who tried it, you might want to build some core strength first as the resistance can be intense!
