If you have never used a stinger before, I highly recommend. For building paper its the only way to go especially if in a high wind area. Quick and easy. Most of the problems I have with it are operator error. Well thought out system and I highly recommend it!
I would have given a 5 but it is somewhat lopsided and is hard to index at first but once I got used to it,I had no issues other than the normal finicky tab feeder sometimes malfunctioning. The convenience of this makes it well worth the money to me.
