## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great for guys with a 44 inch or larger waste,
  

*by M***5 on Reviewed in the United States on November 2, 2016*

So far so good, I've actually owned this product now for approximately one month. Unfortunately I have not had a chance to test it out in the gym but I do use it here at home with my ab coaster to do my abdominal and oblique exercises. This product does not fold up while exercising like others I purchased nor has it shown any where or tear. Again, I have not yet had a chance to use in the gym so I reserve the right to amend my review if I start to see any changes once I use it in the gym. I personally do not listen to music when I'm working out so the pocket for your phone is not really anything I would use. While others may see this as a benefit.

### ⭐⭐⭐⭐⭐ 







  
  
    Waist trimmer with pocket. Great idea.
  

*by K***Y on Reviewed in the United States on December 24, 2015*

I ordered this as a gift for my husband to wear when working out at the gym. The pocket is awesome. He now has a place to put his phone so he can listen to his music instead of the noise that they gym plays. This product came with a website link that gives detailed information on how to properly wear and care for it. It seems to fit well and is not overly bulky under clothes. I will update review with results from use.
