CH38-2 Cap Staple Hammer Tacker, 1" Caps, 3/8" Staples for Roofing Underlayment, Housewrap, and Insulation (STINGER 0136400)…

This tool worked very well. I was hesitant to buy it based upon the negative reviews. I found it easy to use and effective for stapling Tyvek to new construction walls.It is a little confusing to set up the first time. Here are some tips1) The staples load from the back of the tool. You have to open the hinged cover for the green discs to find the staple tray. Once found, it is just like any other staple tool.2) To open the hinged cover, Pinch the green side of the cover, making a C with your thumb and index finger, at the middle of the circle. Then pull up gently. There are simple plastic tabs that hold it closed. Sqeezing the cover pinches the tabs in so they release.3) Place the roll of green discs temporarily in the folded out green cover while threading the green discs into the bottom of the stapler. The green discs should come off of the TOP of the roll. Once threaded, move the roll into the black half of the tool and then close the green cover.4) Once you get the green discs partially threaded into the correct opening, you can get at them through slots in the bottom of the tool. Use a spare nail or screw driver to advance the green discs until one is completely out of the end of the tool.Using the tool is simple. Hit the tool like a Hammer against the Tyvek. The staple penetrates the green disc. The green disc tears away from the roll. There is no cutter necessary or provided. The weak plastic ties between discs simply break.After striking the tool, pull the trigger one time to advance the next green disc. Sometimes it doesn't feed out correctly, and pulling the trigger multiple times still won't advance the disc. It is not a big deal. Turn the tool over and using your finger nail through the slots in the bottom, advance the green disc. My experience was probably about 25 good feeds, and then one mis-feed. Simply advance it manually and it continues to work fine.

These stingers are great tools, with smooth operation, vey impressed with it so far.

Best invention ever. Had to tarp the house after a tornado. Regular staples ripped off. This thing works great. It comes with staples.

This works great for tacking up house wrap as long as you use it correctly. I suspect it with work well for shingle underlayment also. There are a few things that could be better such as easier loading of the caps. If you want something that auto-loads then this isn't what you want. Also if you staple at the wrong angle it won't cut the between the caps and you'll wind up pulling out a string of caps and you'll be cursing at it. Be sure to get the right size staples (3/8") for this one. If you select the recommended bundle the second box of caps and staples were wrong so watch out for that. For the money and what it's needed for it does a great job.

I, too, was puzzled by the negative reviews. Sure, it takes a little patience to feed the caps, but not really that hard. There is a clear stop where the cap goes under the staple. I had very little problem centering the caps and a quick hard blow drives the staple and detaches the cap. The lever does a great job of advancing the cap and a flick of the thumb will loosen any that do not clear the cutter. I found it much easier to use and less of a strain than most pneumatic nailers, including my air staple gun. I also don't understand how it would be hard to hold, as the cap cover fits right in the palm of the hand. This tool made it easy to install synthetic roof underlayment and I look forward to using it when I install my Tyvek house wrap. I guess I could give it 4 stars because of some of the loading issues and occasional misfeeds, but because of the uniqueness of this tool and my intention to counteract some of the overly negative critiques, I stand by 5 stars,

I am a licensed contractor and when I saw this stinger stapler I got excited. This product seems like a wonderful invention. But to be totally honest it's down right terrible. Not worth the money or time it takes to make it work. If the stapler does not cut the button cap for some reason it will pull the roll of unused caps out until you notice it. Then you must cut the unused caps off with a knife and either keep them for later use or throw them away. It will not use the last cap out of every roll and it must be hand fed to get the roll started. If the stapler does not strike perfectly square your cap will not cut and then it becomes a hasle. This product is HUGE DISAPPOINTMENT. Not ready for mass production. They need to go back to the drawing board and figure out a better design for the cap dispenser.

Once you get use to using the tool it helps very quickly to wrap houses.

I read all the negative reviews and was hesitant to buy this, but there's really not a lot of other options, so I went ahead and gave it a shot. I listened to the other reviewer that said to get this one instead of the autofeed version, and I am so glad I did. It is incredibly easy to figure out how to use, right out of the box. The caps are easy to advance to exactly where you want them to be with the pull trigger, and you just hit it against the wall and it staples perfectly nearly every time. I did not have any problems whatsoever, and feeding the caps is very easy with the trigger.Definitely worth the price in the time you'll save by using it.
