Very impressed- the items I ordered are guides for Lishi key cutting pliers (i.e. for cutting a key for a lock). I got two different sets/types of guides in case one didn't work out and both were perfect. The cuts (or bitting) on keys have very small differences between them- in this case 0.15 inches- so if the guides are off by a small amount the cuts are wrong and the key doesn't work. The vendor did a perfect job and the guides work great. If you are on the fence about trying Treatstock, give it a try. I couldn't be happier.
