If this is for toughish work then it's no good. I had one. Quite often the staples stick in the magazine and many of the ones that actually came out were deformed where they entered my motorcycle's seat pan. This is due to lack of power. I had the same problem with one I bought from eBay that had 'good' reviews. Then my dad bought an air compressor and I decided to buy myself an air stapler. Fantastic ! Every staple enters cleanly with no fuss. You may want to buy one with a thin nose that can get into narrow gaps. Only £50 but you need to buy a compressor too although once you do a whole new world of powerful air tools is opened up to you.
I agree I have this same model and used it throughout the house with the skirting. Nearly every nail needed to be punched in and then filled but I was planning to fill anyway so going around punching them in was not that time consuming anyway. So for the Diyer I’d highly recommend and put all your force and body behind it to give it the best chance of going all the way in!
It was turned up to max, used to this feature as I'm a carpenter and I've got a dewalt finishing nailer which is used a lot, only got this as the dewalt isn't compatible with the length nail I needed for the job
There’s a little dial thing at the bottom think that adjusts the force it uses on the staple/nail turn that sucker up.
I had to make some shaker style wardrobe doors recently and purchased this to pin the panels into the rebates while the glue dried. Even though the timber was softwood there was a few times that the nails didn't go all the way in, not a major issue as I just punched the nails home. I can't complain to much as it done the job I bought it for but I would agree with others that it's more a stapler than a nail gun
