Good nailer. I've driven nails at a maximum pressure of 90,100 and 120psi on a Hitachi EC12 supercharger with no problems. Beautiful and compact, the gun allows its user to get into hard-to-reach places that other installers can't reach. For example between bolts or blind nails blocking between joists. The depth of the drive is adjusted by a large aluminum dial located just above the gun. Under the pistol, just in front of the trigger, is the torch's fire button. You have to press the IN button and then slide the switch forward to pull the trigger or back to fire at close range. A rafter hook also comes in handy when working on ledges. I used standard 21 degree frame nails with no glue. The gun shoots plastic nails at an angle of 20-21 degrees. Just in case, I looked for repair kits. Repair kit numbers: YK0444 and YK0445. Depending on which one you need, they cost anywhere from $26 to $38 when you shop. I needed a quality nailer and didn't want to waste my time and hard earned money on a poor quality gun. been there, done. Senco got down to business. Very happy with my purchase
