On the other hand
I saw this review so had to put in my 2 cents. I LOVE this adhesive!! I have been a die hard dotto fan, but when I tried this I fell in love with it. The refills drop in and it's amazingly easy to load, it never gets stuck or gummy from adhesive sticking to the applicator. I requires much less pressure to roll and I have not had the problem with a line from the roller edge indenting my pictures.
I LOVE IT and have changed by adhesive to this.
