Both nailers work perfectly after a few days of use and a few thousand nails. But a few words about the seller, CastleRock Tools: I'm doing some rare work to frame my attic and soffits and was looking for a nailer in the familiar "occasional" tool category, something that would work. but not in the wallet. Realizing that there was little space in the attic for some work, this combination of frame and hand nailer seemed like a no-brainer. Unfortunately, an issue with the stock labeling meant I only received the nailer, not a hand nailer. piss off! I emailed and was surprised to get a response from Mike at CastleRock Tools within an hour. He asked me to email some pictures to see what I actually received, suspected a problem and sent the missing nail gun directly. All on the same day. Any veteran of buying budget tools knows that this kind of support for such tools is very rare, if not unheard of. I've also noticed a large number of great answers that CastleRock provides in the questions section. Thank you CastleRock, I am very satisfied. Buy safely friends!
