I am very pleased after taking a chance on this little red stapler that I needed to refurbish my IKEA (made by Natuzzi) Arild leather sofa. It did a fine job stapling the webbing, leather and underside cambric. A cheap little harbor freight 3 gallon air compressor and a hose was all I needed to get the job done. The included staples and machine oil were a welcome bonus. I really needed this pneumatic stapler as I couldn't have stretched the webbing and stapled it with a manual staple gun.

Bought this with the intention of using for upholstery. Worked for a few rows of staples then started sticking badly. I took it apart, the gasket was ripped and the internal parts all have so much friction, the slide does not retract. Very poorly machined parts.Total waste of money.

I'm a weekend DIYer. I needed to upholster my dinner chairs, this staple gun exceeded my expectations. Only thing I didn't like was the safety feature it has. But for the beginner I guess you need it. But all in all it's a great gun for the home, granted you have a compressor

2nd. This is an update!; why I changed to 5 stars:After contacting customer service via email this seller bent over backwards to make sure I was a happy customer. And because of that I would not hesitate buying from them again!!1st. While using this staple air gun fallowing instruction’s on oiling every few minutes it just stopped working! I was laying down some new deck vinyl for my pontoon boat. Using SS staples around the edge and I loved it!!! When it was working, it was great! Went through one box of 1,000 staples. Started to staple the aft end of the boat vinyl and it just stoped popping. After fallowing the repair instructions to the tea I still couldn’t get it to work. After replacing all O-rings chicken for any burners on the cylinders checking the trigger mechanism and having more than enough air pressure I just couldn’t get it to work. That’s why I am giving it a 3star. I would not recommend this item to anyone that needs a air stapler for longer then 4 months.

Broke after six months of ownership...5 of which it sat in storage....so I literally used it 4 times...one year warranty but amazon wants nothing to do with it and seller doesn't reply.**Update...seller finally replied after a few days and advised that there was no warranty. Clearly a contradiction. BUT....advised he would send a replacement once they are back in stock. Will update once it arrives. The item appears to suffer air leakage around the trigger due to o-rings not sealing correctly.Third update.... Replacement was mailed out 5 months later after several attempts to reach the seller. I sold the replacement because I had already purchased one from Home Depot. I loved the stapler when it worked. But it was easily a paperweight shortly thereafter.

Looks good and sturdy when you receive it, then works fine when first plugged to air so you can oil her up with the supplied little bottle, but then when staples are put into it.. (tried all 3 supplied stapled lengths) it just will not work at all and if you try to open the back end with the supplied tool to see what’s wrong, well you just end up stripping all the bolts because they just seem to be on there FOR GOOD! And I’m a very « handy » guy just so you know.. So DO NOT BUY!!!
