I did purchase the Extra Hand, and it does work. Used hanging crown moulding. Using it to hold the other end of the Fat Max tape measure, I had to make sure the blade stayed flat, if it went on edge, it would slip between the layers of the wings, no big deal. It did hold the other end of a 5" crown, 16 foot lengths, but one time I let my end down a little too far and it did pry it off the wall. I used it on painted, plaster walls that were a little irregular, and it held well enough. I am sure it would hole the other end of a long lever, and larger crown, but I wouldn't rely on it for much more. Overall, it did make life easier for me, as I was working by myself. Although $40 something seems like a lot for what it is, it certainly is cheaper than having a helper. Glad I got it.
