it's amazing. this is my first time to use banding tapes like this, I am so lucky to find it works well for me. the tape really help to protect he joint tissue and relieve pains. and it lasts very long. I will definitely buy more.

Perfect kneeboard for a student pilot. Has all the bells and whistles (more than I need personally) to alternate to either knee depending on your flight profile.

This fan is just okay. It does it's job as a fan and it's a good price, but I feel that it is cheaply made. Mine arrived today and one or the side caps was already broken off. I purchased brand new, however, I may have gotten a slightly used one that broke upon assembly and was sent back without inspection. It doesn't affect the motor or the blade, but it's kind of an eye sore. Guess it's time to pull out the super glue and suck it up.
