Review on Lang Tools 7578 Automatic Adjuster by Jay Lee

I'm a heavy equipment mechanic with over 20 years experience, I've just started working with trucks and I needed this tool. I've been using it almost every day for a week now. It is made of fairly soft steel and bends very easily. I'm going to run a bead around most of the edge of the tool to add stiffness. If it's still too soft I have some cement putty that I'll use to stiffen the outside of it. It frustrates me that the R&D department obviously came close to identifying a need and either never tried it in the real world, or the engineers were responsible for field testing and couldn't confirm its suitability for real use. I will not buy anything from this manufacturer again.
