While I appreciated my shirt arriving on time I ordered a 2XL shirt and a large was shipped to me. The shirt clearly states LARGE but the sticker on the outside says XXL. Your quality control is not good and has messed up a birthday gift.

Ex Output:
negative

One of our bedrooms doesn't have a light switch, this is the perfect solution!! Plugged a lamp into the outlet and then stuck the on/off switch to the wall by the door with a command strip and it works perfectly.
