I love this product because it holds a lot of adhesive; you are not constantly looking/changing refills. The adhesive itself holds very well. You can also get different sized tape for the same tool. The two things I don't like about it is that the adhesive is permanent--once its down, its down. Also, the gun is kind of big and bulky, so not real easy to carry around. But, I think the advantages far outweigh the disadvantages. Definately recommend.
