[EX Q]: Easy to use mic for phone/pc/laptop. Great if you just need a small mic and don't want to spend a lot of money. Works well. Comes with velvet carrying bag. *disclaimer: I received this product for free in exchange for my honest and unbiased review*
[EX A]: positive

[EX Q]: I've been having knee pain for the past few months so I decided to try this support brace. I can't believe how much support it does provide and my knee pain has gone down significantly. It's slim so you can wear it under pants while at work but also looks fine with shorts. So glad I found this and it is helping with my knee pain!
[EX A]: positive

[EX Q]: Received my bikini bottom today. It fit perfect. Covers well we're it should. Tummy control. Like the way it shows off on the sides just a little. Matches any top I put it with. Easy to move in very comfortable.
[EX A]:
positive
