My dad bought me one of these a few years ago and I really liked it until the moment I cut the tape with a shovel. I ordered these as they are the same model as my old one and I am very disappointed with what has become of them. I could tell straight away that the case was cheaper than my old one, but it wasn't a big deal. The problem was that after a few uses, the auto-lock started to slip. My old one has been used thousands of times and has never moved. This will slowly begin to contract as you expand it. Since there is no way to manually block it I will look for another brand to replace this one.
