Ahh yeah, I’ve had plenty of issues with that too. I’ve no idea when it started to just work for me. I just started to give ‘er an angled yank and it started working. It kinda’ reminds me of the stories of how F1 cars perform. They have so much down force that you pretty much have to rocket through the corners to keep grip up. If you try to tip-toe up to the edge like with a normal car, you’ll just slide out before you reach peak performance, bacause faster means more grip.

Like with the tape guns, I think some require you to be a bit rough with it and the little flappy plastic thing, or else it doesn’t bite enough to cut the tape.
