Mildly Infuriating

You must either have a bad one or you're using it wrong. The one we have is amazing.

Cheap ones are s##t, worn out ones are also s##t. Adjusting the tension on the tape roller is a fine art as batch to batch the glue can change.

God I need to get out more !

Probably using them wrong. These things are great if you have a lot of boxes to tape and need it done fast.

You're likely using it wrong. They're great, when you have a good one.

They're less bad if you use quality tape.

They are super cool. They can be used with only one hand for any sealing-related jobs. But you need to practice with them for 5-10 minutes before it "clicks"

It takes some practice, and you have to understand how the blade engages based on the angle you’re holding it at. If you can figure that out, these are awesome. It doesn’t even have to be a fancy one or more expensive tape.

Fairly confident you are using it wrong.

Years ago I worked 2nd shift in a bindery at a medium-sized print shop. One day when I came in at 3 pm, the 1st shift straw boss announced that we had to get a certain job folded and boxed and ready to ship by 5 pm. The asshole who ran the folder on 1st claimed it was "all set up and ready to go". It was not. So to add to the frustration of the situation, this one c*nt, whom her co-workers called "Pricess Smith" because she was fucking the married supervisor who's name was Smith (no, not really), used to hide one of only two tape guns in her toolbox. So after wasting an extra 10 minutes looking for the one remaining tape gun (after 15 minutes finishing the set-up of the folder), we barely got the job folded, boxed and palletized in time for the truck driver to load and deliver it.

Later, once we had time to breathe, I was still feeling salty. I broke into her assigned plastic toolbox by removing the hinge. I took out "her" tape gun (not hers. just to be clear) and taped it up in a huge wad of tape, then put it back and put the hinge back on, and put the toolbox back where she kept it.

The next day, we heard that she cried about it and even went to the company VP about it. After placating her, according to one of the other supervisors, they all laughed their asses off.

Bought one when moved to a different country and had to pack a lots of big boxes.

Its great time saver, only downside is how god awful loud they can be.

They're fantastic for boxes.

The ones where the plastic shield pressing against the box makes the little teeth plunge into the tape are friggin' orgasmic.

Managed to perfectly perforate my chin with one of these as a foolish 16 year old in my first job. Entirely user error (I'll let you guess how) and left my chin looking like you could tear it off like a postage stamp for weeks after.

Safe to say I wasn't allowed to use it again after that, so my only experience with these is that they're terrible - though that's probably not a fair judgement given the circumstances 😂.

A good one of these makes moving much easier and less painful and aggravating than the cheap ones or the plastic things. Just don't use it too long, take breaks if you're making a lot of boxes at once. You can stress your hand and wrist using it.

There's also a technique to it, which you can find examples of online. Try a few ways and see which works for you. Also practice helps. 😁

Practice helps.

I use them everyday. I work in logistics. Trick number one is to have special tape that isn't as loud when unrolling it.

Tip number two is just use your finger to put the first bit on, hold it with the finger and do the rest. At the end, push the top part against the box to make the knife cut the tape.

Wipe over the tape with your finger if needed, some tapes and kinds of carton don't have much holding power. If you move your fingers over the tape, you'll heat up the glue and it will stick better.

don’t use UPS brand tape for these things

You got one of the nice ones there. Play with the tension on the wheel. If it's too tight the blue metal piece will bend and that causes the tape to slide off. If it's an old worm out tape gun, you can bend that blue metal back pretty easily.

I think they're fine but kind of unnecessary unless you're boxing a bunch of stuff. If you're moving or do online sales on e-bay or whatever it might be worth picking up a quality one but otherwise just buy a roll of packing tape.

How's it not working for you?

The only way I’ve been able to get these things to work is to put my thumb on the tape roll so it stops rolling out and I can cut it with the blade part. I have historically had the same issue as you though.

If you don't have the tape facing the wrong direction, it should work effortlessly. Many fail to understand the razor and plastic shield mechanism that leverages tension to make a clean tear tho. The tape can melt and be tough to use. You could also have a low quality item technically but even cheap ones are fairly manageable for a while
