Okay so I've been using this ab roller for about 2 weeks now and here's my real thoughts:

First impression? The packaging was kinda basic but everything arrived intact. Assembly took me like 15 minutes while watching TV - not bad at all. The instructions could be clearer though, had to guess which screw goes where.

The GOOD stuff:
- Seriously targets my abs in ways regular crunches never could
- Actually protects my lower back (I have old sports injuries)
- Weighs nothing but feels sturdy during workouts
- That satisfying roller motion makes workouts feel smoother

The NOT-SO-GOOD:
- Padding could be thicker (I put a towel under my neck)
- Takes some practice to get the form right
- Makes weird squeaky noises when I go fast

After 14 days? My core feels WAY stronger already. Worth every penny if you stick with it!
