5 Stars
This one exceeded my expectations!! It’s worth a try.
OMG ... it’s better than I thought! I’m a little shocked. I was looking for a smaller sweat waist trainer and decided this one might work.Let me start by saying that I’ve worn waist sweat trimmers for over two years. They make a difference in inches lost on my waist size because I wear them consistently every single day. But more importantly, I wear it everything single time I workout which is 4 or 5 times a week. If you’re disciplined, eating, and working out, sweat waist trainers work by giving you a little extra help in addition to everything else you’re doing. However, if you don’t break a sweat when using it will likely not make a difference.Before this one, I’ve always used the one design with a single wideband that you wrap around with the big velcro attachment (specifically the Sweet Sweat brand). As I’ve got smaller, it started to bother me that my waist I looked larger when wearing the other brand causing me to wear it less. Enter Mermaid Waist Trimmer!! It instantly made my waist appear smaller, support’s my back (which I did not know was needed but a bonus), and while I’ve not yet worked out in it, I believe it’s going to get-it-done there too. I’m still wearing it now and don’t want to take it off.UPDATE - 11/7/20I love this waist trimmer! One of my best purchasers from Amazon in terms of price versus value. I wear it when I work out and makes me sweat more than any other trimmer I’ve used. Worth every penny!!Let me get on my “soapbox” for a second ... In my opinion, Amazon has started to be touch-and-go over the last few years where “reviews” are questionable at best and you don’t know if you can or should trust them anymore. So I’m making a point to leave reviews when I come across a quality product that does what it says. So I’m a real person!! I’ve actually purchased this with my own money and no one sent it to me nor am I being paid in any way. If you want more REAL reviews on Amazon, make sure to make that THIS ONE was a “helpful” review. I believe it can help get it to the top. Also, start leaving reviews when you come across a great product!
