Very handy but be careful not to drop it on hard surfaces. Once the roller or spool is bent out of alignment the tape roll is prone to leaving the spool.
I have used many tape dispensers in my time and they have all been easy to use and well constructed. This one is not. The tape sticks to the dispenser. It does not tear the tape cleanly or easily. And it doesn't have a tape guide as do quality dispensers. This was a total waste of money.
