[EX Q]: I slouch at work sitting at a desk all day. Was trying to find a good solution to help alleviate the slouching and back pain. This posture corrector has definitely helped! I am sitting straighter and the pain has lessened.This posture corrector has given me strong support for my back, without restricting my movements.
[EX A]: positive

[EX Q]: Get the Otium Bluetooth headphones. I mistakenly bought these thinking they were the same because they look identical but they were not the same. Bluetooth connection would break up periodically. Sound was average and they broke in half when I pulled them out of my gym bag. Poor overall quality.
[EX A]: negative

[EX Q]: Don't waste your money on these. Extremely thin and cheaply made. Arrived already cracked and damaged. You are better off to spend a little more for a better quality product.
[EX A]:
negative
