“The Prop-Jack is a clever solution and an elegant design. It’s lightweight, and easily and effortlessly manipulated with one hand. I can literally tighten or loosen this thing with one finger! The way it holds itself in place means you can make little adjustments here and there without it falling into the body of the guitar. That feature also makes it handy for dry runs for complicated clamping. The rubber feet are firm enough to stay put, but soft enough to not leave any marks behind. Both sizes are useful on their own, but I’ve found a set of four gets me in and out of even the most complicated internal repairs. These are a joy to use!”

SF international, seems all right, except for the fact that their prices being bulk, should be lower. The opposite is true. It was cheaper for me to buy from Amazon, and their Customer service is really obnoxious, they keep sending messages all the time, pressure sales. Bummer their products looked good.
