Review on Convenient 9V Battery Case Holder with Cover and ON/OFF Switch – Pack of 4 by Tim Shah

packed backwards. The part that holds the battery and very thin wires has an on/off switch. I tried to attach the item to the cosplay costume but you have to attach the bezel so you actually have to remove the whole big case and the very very thin wires to change the battery. Typically, the case itself can be attached, and a small cover can be removed and removed to allow for battery installation. Not this reverse model! Also, there is no buffer in the case to keep the battery in a charged state. I had to cut off a piece of foam rubber to fix it.
