I was delighted with this purchase when I first received it. I've used it to install small half inch staples into Tyvek and then translucent rolls of fiber plastic that are used to hold the lambswool insulation in the carcass. It's also great for a variety of 18 gauge nails. I used it for 2 inch trim nails when installing cedar. My issue is that after a month of use (added air oil every day we used it) the cleats became stuck on the inside of the rail they were pierced through and blocked the job. Initially it was only 1 in 100 staples but now it's closer to 1 in 20. I think the metal used is too soft. Hence my rating going down from 5 (excellent) to 3. Still positive but not a long term investment until they improve the quality of their steel.
