I've labeled this "so far, so good" because I've had other tape runners behave themselves for the first few weeks before I started having problems. I've used this one far more than the others that I've tried because it's actually worked better than the others. Hopefully it will continue to work well since the price was right and I have refills (a friend gave me some, thinking I had this dispenser. Since I didn't, but didn't want to lose the refills, I bought the dispenser.
I have only used this a couple of times since I received it. It is very comfortable in your hand and the adhesive dispenses very easily. Knowing this is a "refillable" item helps me so I don't have to purchase the whole unit every time...and all I have to purchase is the "refill". Another feature is being able to pull out one cartridge and pop another (permanent & repositionable) tape.
I'm not a big tape runner person (I prefer dots) but this one is great. the whole tape sicks to the paper and it has feet to run across the paper. The stamp part doesn't work on everything (like felt) but works on all solid surfaces. I will be using these more often. I also bought the pin one that is dots.
I love the feel of this, very easy to hold onto, but not so big that it's in the way. It comes fully loaded and ready to use, just pop off the cap and away you go... What I love is that for smaller spots, you just push down and it releases one little sticky square of adhesive. Very cool product..
