The best adhesive solution I've found (and I've tried them all)
I've been through almost every kind of tape runner that is produced for scrapbooking, and found fault with almost all of them. My Scotch ATG 714, however, is hands down the best tape runner or gun I've used. First, the cost is extremely low compared to other runners. Second, it is very easy to load and use. There is a little bit of wrist action you have to learn when "releasing" the end of a run of tape, but other than that it's pretty much intuitive. Third, since each roll of tape is 36 YARDS long, I don't have to constantly keep adding refills. I've gone for two 6 hour crops on the same roll of tape with some left to spare. I also like that the refill produces very little waste- just the tiny core and the backing paper is disposed of. I've disliked other tape runners that seem to replace half the mechanism when you install a new refill.
