Now first of all the ADtech:
there has been a growing problem with these guns. I think the reason we are seeing so many problems with one kind of brand is because walmart changed to this brand of gun about a year or so ago ( that I have noticed) I also believe joanns now carries these as well. I think that's why we are seeing so many people having issues. There easy to find and CHEAP!
I have used the adtech with no problems but they like to drip a lot or "freeze" were the stick gets jammed. They sometimes like to "crack" and makes sounds as the glue gun warms up. I haven't had any problems with blowing up or fires, but all my ADtech guns I had I ended up throwing away. Mine just would jam up constantly and it was very frustrating in the middle of furring when I cant get any glue to come out.
Another kind of gun I have used is a Stanley( there yellow and black) I loved it at first, and came with a free silicone mat to catch the drips. I bought this gun at my local target for about 12 bucks. but after i used it for about a month it started to dripped like crazy then after a month or two then just died for no reason.
Out of all the guns the only one I seemed to have the littlest of problems was the Surebonder:
One Surebonder I had for 10years with 0 problems. It did drip time to time but not as bad as some guns( the Stanley gun would leave pools of glue). That gun was a regular Surebonder. They are usually blue with a orange cord. But there known to come in different colors, such as red or black. But are mostly common in blue. I bought mine at walmart, some still carry them, but I've noticed it's mostly the ADtech at walmart now. You can find Surebonder at michaels and at joanns.
But by far my favorite gun to date is a industrial gun:
About 6months back I up graded to a Surebonder industrial gun. Only two big differences; it's bigger with a huge trigger, and the wattage is 80 instead of 40w( which is the most common for a high temp gun sold in craft stores/walmart)
The industrial was more expensive (40) but so worth it! Never jams, always hot ( maybe a little to hot gotta be very careful!) and never ever drips.
Before I would go threw the smaller guns quickly. I usually try to be safe then sorry and when a gun starts to look brown and discolored around the tip ( not from fur melting on the tip itself but around the end) I would usually toss them. So far I haven't had any issues with guns exploding or catching fire (knock on wood) so I try not to risk it and toss it before it looks to be a problem.
These are just my experiences with these guns, but everyone has there own opinions and experiences. Surebonder just works for me!
Check out amazon they have all kinds of glue guns for great prices if your willing to wait :) but you should be able to find Surebonder guns at local craft stores!
Just do a little research and I think shelling out a few more bucks or a good gun is better then risking any issues in the future. Even more so if your making more then just one or two suits.
Hope this helps! Feel free to ask me any more questions! And please feel free to speak of your own experiences! And your favorite brands! I think it will help a lot of people choose what might be best for them.
