So far the thing has been reliable. I use it to install 9/16 solid oak wood. It feels like the instrument is well made. I had one stuck, but it was my fault when my compressor pressure dropped. I worked the gun at 50psi on the tool line. ONE SUGGESTION: I've found that by installing a swivel adapter you can bring the walls closer, allowing you to remove an extra row or two that you may need to nail. The standard direct air line nozzle can prevent the device from approaching when you connect it to the line.
