Works as advertised. Buy Freeman brand staples. Universal will be promoted at least once per reboot at the Revain Jam. The difference in price is negligible, so IMHO it's better to take OEM staples. Oil at least once an hour (only 4-5 drops). I use a 4.5cc 3 gallon portable compressor. feet per minute and it works fine. If you're going to be used for production work (i.e. high volume, fast stapling) you'll need a larger compressor than I think is adequate. I only place 4-5 staples per post and my compressor keeps up with the gun.
