This is not an accurate thermometer. Consistently get 96 degree readings. It shorts out frequently. Does not save last temperature. Very disappointing.

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!
positive

I have no regrets with this keyboard. I was definitely not looking for this keyboard originally. I was going to settle for a keyboard that looked like a typewriter. I didn’t know I was settling though. I didn’t know I wanted one with crazy lights on it. I am shook to my core. Everyone has asked where I got the keyboard from.
