ThermoWeb is my favorite tape runner. I love it because you can run the tape fast or slow over your paper and it will always work.(some you can only use at a snails pace to get it to adhere properly.) I also love that you can you run it straight or curvy down your paper, as well.
I have used this runner for the last 5 years and I wouldn't use any other. I love how is curves and turns makes it so easy. I also love that you barely have to touch it to the paper, there is no pushing it down it just glides across.
I really really like this product. The tape flows freely when in the dispenser, and it follows curves and circles quite well when applying. Doesn't gum up or fall off the guide like others I have used. Changing the refill out of the dispenser is a breeze...open dispenser, pull out empty refill, set new refill in and close dispenser. Very sticky, haven't had any papers or pictures fall off a layout yet!
