Let me start by saying I've tried my fair share of waist trainers, from cheap drugstore finds to high-end brands. The YIANNA Waist Trainer Belt caught my eye with its promising features, and after weeks of testing, here's my honest take.

The Good: This belt delivers serious compression! The neoprene material feels premium and creates that satisfying 'snatched' effect instantly. I particularly love using it during workouts - the back support is legit when doing squats. The adjustable Velcro is a game-changer compared to hook-and-eye closures from other brands.

Reality Check: Sizing is TRICKY. Like several reviewers mentioned, there's zero stretch in this belt. I'm 5'5" and had to exchange for a larger size because the medium squeezed my ribs uncomfortably. Also, the front panel could be wider - it tends to roll during intense cardio sessions.

Sweat Factor: Oh boy, does this make you sweat! I wore it during HIIT classes and could literally wring out the belt afterward. While great for temporary water weight loss, don't expect miracles for permanent fat reduction.

Comfort Tip: Always wear a tank underneath unless you enjoy Velcro chafing (ouch!). The material is breathable but gets HOT - perfect for sauna workouts but maybe skip it for outdoor summer runs.

Final Verdict: For under $30, this is a solid waist trainer that actually works as advertised. It won't replace proper diet/exercise, but gives fantastic temporary shaping and decent back support. Just size up if between measurements!
