I can't say I didn't like something. This tool worked flawlessly for me when allocating my 1200 acre roof. I had a Hitachi and my Valu Air. I loaded them up and when one was empty I grabbed the other and moved on. If you're a pro I can't tell you how it will work for you. But as a homeowner looking for value and reliability, I would suggest giving it a try. Apparently the money is to blame. IMHO.
