I was sooo excited to find the glue dot dispenser at a local store and get to try it out. Yes, it is a convenient little package to have the glue dots in the roller. And there is a cool little knob on the side that allows you to advance them one at a time to use as you normally would a glue dot. But, they are not refillable. Such a waste to just have to throw the whole thing away. I don't think I will be buying anymore unless they come out with a refillable version, one that is a bit friendlier on our environment.
