I received the product in a timely manner. It was as advertised. I have used it a number of times and it works well although I haven't gotten the results from it I had hoped for. No fault of the seller or the product though.

I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.

I have been using this for 3 weeks now and while I have seen no difference in my measurements, my posture is definitely improved. I have also lost about 6 pounds, which is likely due to my combination of diet and exercise, but I have also been wearing the corset at least 4 days a week for up to 9 hours at a time.I am 5'9" 150 pounds and I bought a size Small and it fits how it should, super tight. I look forward to eventually going in to the second hooks.My only complaint is the SMELL. It smells like rubber and while I hope no one around me really notices, I notice. I wear a wrap around my midsection underneath it, but after all day the smell still gets on and stays on my skin.Otherwise, the construction is super sturdy and I anticipate only needed one for a long time. Hopefully the smell will fade with more hand washes...
