Let me start by saying this waist trainer has been a game-changer for my workouts and daily wear. The neoprene material really does make you sweat - I've literally seen puddles after my morning jogs! The double belt system provides serious compression without feeling like you're being suffocated.

The steel bones are a standout feature. As someone with occasional back pain, I appreciate how they provide support while still allowing movement. I've worn it during yoga sessions and weight training without issues. The zipper + velcro combo keeps everything securely in place - no annoying roll-up like some cheaper trainers.

Now for the not-so-great: sizing is tricky. I'm 5'6" with a 29" waist and ordered medium based on reviews suggesting to size up - perfect fit! The length covers from underbust to hips beautifully. However, if you're between sizes or have a shorter torso, this might feel overwhelming.

After three weeks of consistent use (4-6 hours daily), I've noticed my posture improving and my waist measuring about 1.5 inches smaller. It's become my secret weapon under work clothes too - gives that snatched look without discomfort.

Pro tip: Always wear a thin layer underneath! The latex can feel intense against bare skin, especially during intense workouts. Also, hand wash only - the material holds odors if not properly cared for.

Would I recommend? Absolutely, but with caveats: measure carefully, expect an adjustment period, and don't expect miracles without putting in the work yourself. This is an excellent tool, not magic!
