[EX Q]: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.
[EX A]: negative

[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]: Bought this in King size. When I opened the box I questioned my choice. It looked like there were a thousand pieces and we would be all night putting it together. SURPRISE!! it took about 45 minutes at the most and that was because my boyfriend insisted on helping. Without him, maybe 20-30 LOL. It was that easy. I was stunned by how strong the bed was. We are both over 300 lbs. and it didn't even creak. We thought we needed a new mattress. Turns out we needed the platform on this bed. I would give this bed a 10 if I could. I will follow up on how it holds up to our weight for other plus size folks looking for a good bed, but for now, it's a 10 for me.
[EX A]:
positive
