Love ur products but this one is NOT good. This photo is 8 hours after class. I’ve had this mat about a month and the stains never completely disappear. I’m a woman and I do sweat but it’s embarrassing to see the outline of my body at the end of class...to the point where people start staring at my mat and at me. Yuck. Please let me return for refund if possible.

I have read all reviews before I bought this, luckily, I received an item with any issue. The stun gun can make loud noisy like other buyers said, the flashlight is not bright enough, but It can blind the attacker. I have try the stun function and my friend said it make a huge painful sense.

I'm so extremely happy with my new bluetooth headphones! Very happy with the quality and you cannot beat the price! I use mine for listening to music while I exercise, whether I'm at the gym or going on a jog with my dog. Great sound quality and noise cancellation is fantastic as well! I'm happy with the hands free ability to control my music as well...much better than not being able to control my playlist at all. They're also pretty comfy and I didn't have issues with them getting wet while I worked out; nice and dry the whole time. If you're looking for great quality without spending $100, these are definitely worth the $20.
