I pruhased this because of it's unsusual design. I even had plans to have it engraved as it in my opinion had sort of a classy design and looked in the pics to be of better quality. That is not the case. The modern Tetris design while looks like it could be metallic is not. It's a cheaply made sticker. It does not stand up inside your pocket with loose change or keys. Mine looked scratched/soiled when I took it out of my pocket. Using mild soap and water I tried to clean it and thats when the fininsh came completly off. I am so dissapointed. A waste of money.

Really nice cart battery. Works well!

works great...so much easier to carry...keeps a charge...no negatives...love you guys

It protects the cartridge and keeps it from getting lint in the mouth piece. You cant tell what it is unless you pick it up and really look at it. Works great and shipped fast. Will buy again.

Enjoying every day
