Eraser works well - but its a little hard on the drill

The eraser works well, however I used a 1/2 inch cordless drill to operate it and I don't think the drill bearings are meant to be side loaded, my drill started to sound funny after a few minutes , so I switched to my Milwaukee 1/2 inch  electric drill and it worked alright. The drill runs at a slower RPM, so it didn't function great , but it did do the job - it just took longer. I used a heat gun to remove the decals and stripes on my boat and the eraser to remove stubborn decals and the glue left behind. So overall it does the job, but you have to use the right tool to power the eraser. It did leave a few scuff marks on the fiberglas, but they buffed out. No damage done.

These are perfect for a planner like me that has constantly changing plans but the eraser doesn't remove completely. Kind of a bummer.

Awkward way you have to unscrew the eraser to get to the lead storage area. Also the cap that fits over the eraser sometimes extends the lead out of the pencil when removed so you can erase.

As the other reviewer stated, it is light and yes it is since it is made out of plastic. Overall I like it since it has the famous grip dots with the triangle shape like the wooden Faber-Castell pencil.

Good mech. pencil but the best mechnalical pencil I've ever had in my opinion is the aluminum Pentel Graphicgear 1000 (.7). It's slimmer but has a nice grip like the dots and just elegant but about double the price. It doesn't feel light but subtantial without being heavy.

This eraser leaves a lot of dust behind on our chalk wall, but it does remove the drawings.

Worked like a miracle until one of my mean spirited 7th graders shoved a crayon into the sharpener.  Now it gets jammed easily and does not bring pencils to as much of a point.  It works on colored pencils, and that is a plus.

I have had this Sharpener for about 2 months in my 4th grade classroom.  It works very well compared to others I have tried in the past.  The only reason I didn't give it all 5 stars is there is a place where the shavings collect and it is difficult to get them out.  If the shavings get in there to compacted then I have to use the air for my computer keyboard to get it unjammed.  When this happens the sharpener stops working until the shavings are all out.  I have had to do this procedure three times in the past 2 months.

These are very cute mechanical pencils. I purchased "Style 1". Comes with a cute lead dispenser filled with refills and has a small eraser underneath the metal cap. Not a great eraser but it gets the job done for small marks with average pressure. This eraser will not stand up well to pencil marks or writing made with heavy pressure- it's a little flimsy but just don't go berserk on it and it should be fine. The pencil itself seems fairly sturdy and I personally find it comfortable to hold.

I'm an undergraduate mechanical engineer and I do a lot of erasing. Specifically, I use mechanical pencils, which at times can be harder to erase than the normal wood pencil. I've tried several different types of block erasers and this one is the only one that really does the job. Since I got this eraser I no longer have messy erase marks all over my paper, and it produces a little less shavings than the typical eraser. The cardboard grip/encasing is also a nice touch because it protects your eraser and makes it feel more substantial. Overall, a wonderful product!

My daughter wanted this, and so we ordered it. Works great for her classroom projects. As an adult, I would prefer something with a stronger motor to resist the pressure my hands apply when using it to erase things. Seems like the bigger hands apply more pressure to the eraser head when it turns, and the motor stops turning. But for a pre-teen or teen like my daughter, this motorized eraser is perfect because she has smaller hands (less pressure).

These work really well. They glide smoothly and don't smear easily. They erase with just enough pressure. My only complaint..they say fine tip but it wasn't as fine as I was hoping. I wanted something that I could use on a dry erase schedule/calendar but these were a little thick. The search continues!

This pencil sharpener by X-Acto definitely sharpens pencils well;  and I like that! The power cord is relatively long which makes it easy to place it just about wherever on your desk you want it.

However, it is a bit louder than I would have liked it to be. Therefore, this wouldn't be the best choice in quiet environments like libraries or school study halls. I also agree with other reviewers who note that the drawer that collects the shavings is somewhat tricky to re-insert after you've cleaned it out; you really have to line the drawer up just so in order for it to fit back in and I would have liked an easier time with this.

Overall, it's not that this pencil sharpener is actually bad; the machine does do its job and the power cord is fairly long. However, it's just not quite what I wanted. If you really want a fine pencil sharpener, keep looking and be prepared for the possibility that you may have to pay a little bit more for the pencil sharpener you want.

Don't use the eraser with the spray, it just smears it around, use a rag instead to deep clean it, should be common sense but obviously...  No issues though.

I am not sure if the unit I bought is defective, but it doesn't work well.  There is a little nylon filament coming from the metal cylinder holding the eraser, and it looks like it should go into the top part of the unit where you click the eraser into use.  But it doesn't anchor itself to anything, and when I click it into place and then back out of the way, the eraser just stays there.  No directions but two diagrams make this unit difficult to install.  When I tried removing it to see if I had done something wrong, the eraser section just stayed in the bottom of the pen, below the spring.  After turning it upside down and shaking it a lot, it finally came out.  I think mine may be defective, but I am going to check out my friend's unit to see if mine is the same as hers.  The eraser is really tiny, but it works.  It also wants to just fall out of the tube.  I pushed it back in really hard, and it may be a little better.  But I will stick to the mechanical pencil unit I like best...a Kuru Toga .7 with diamond hard lead!  Great pencil.

This sharpener handled a huge set of pencils being sharpened in preparation for school starting up. The only complaint is that a lot of shavings gather around the blades/pencil insert hole making it a tad messy. Otherwise it works very well. The indicator light lets you know when the pencil is sharp, but it also automatically stops the blades when the pencil is sharp.

I like this bit holder and would recommend it. My only complaint is the pressure ball on the side doesn't hold the tips in tight enough and the bits fall out of the holder sometimes. I was using a 6 in one screwdriver shank on my drill before I bought this

Everything is awesome, the grip especially. But the eraser smells of some plastic or some kind of burned plastic. Overall its pretty good

Works well to magnetize a too - like a screwdriver -  to  hold small parts.  It comes without instructions but that's okay because it is intuitive.  Just stroke the tool to be magnetized in the proper hole. Be sure and stroke it against the inside wall.  Same with the demagnetizer.  Just stroke in the steps.  I don't understand how this demagnetizes but it does..
