Hope they keep the product quality and price. Ive followed all the directions but doesnt work. Ho finalmente radunato le mie spezie, tutte insieme e in poco posto. Key Volume: Id rate this as a mid-volume key. Surprise/unexpected benefits:1. They can be polished with shoe polish. They are okay but they have some serious drawbacks. They seem to be over very quickly. Great for workin out and back support. I have been wearing it for couple days, its definitely what I need.
