Item exactly as described and fast delivery

A sharp idea.
It works and does not tend to break the leads. It is well-made and makes it easier to use mechanical pencils. Quick and efficient. Can be used professionally.

Great sharpener, but needs better instructions!
These are really effective ONCE you learn how they work. On the box are two - and only two - very cryptic thumbnail illustrations; these are the only " instructions. HOWEVER, a quick dash to YouTube turn out a host of very informative videos on how to proceed. So . . . My verdict is five stars and a strong recommendation for better INCLUDED instructions

Pointy or POINTY
I love how this sharpener has two point options, one is your pretty typical point which is great for writing and drawing. The OTHER option is P O I N T Y, super delicate work because the moment you make contact with paper that point is crumbling into oblivious, or I just don't know what I'm doing. It's very easy to use, drop lead into either hole, shove whole pencil in whole, give it the whirly twirly, and use the white sponge thing to retract led and clean tip. Then proceed with your pencil stuff.

Works ok, but is kind of cheap
This pencil sharpener works fine and suits my needs grandly. However, it feels rather cheap compared to my old Staedtler sharpener. It is also a darker shade of blue than what is pictured. The white thing on the top is also foam, a cheaper replacement to whatever used to be there.

"What's the point"?
This a great little sharpener.The only drawback is it will not fit all mechanical pencils of the same type but it does put a very sharp point. I glued a small magnet to the bottom and attached it to my table saw and it stays handy.

Works great. I wish mine came with directions though.
I originally posted a two star review because I couldn’t get mine to work properly. It really bothered me that I couldn’t get it to work correctly and figured it must be me. It was indeed me. I kept working at it and I figured out how to use this properly. Once I figured it out this thing works awesome. My only complaint is that it doesn’t come with clear directions or at least mine didn’t. Maybe it’s obvious to many people how to use this but it wasn’t to me. Step one: Use one of the two small holes to set your depth for the point that you want, either really sharp or dulled at the tip. Let the lead drop to the bottom of the hole then slide your lead holder till it touches the top of the unit. Once depth is set remove from unit. Step two: Simply place the tip of your lead holder into the large hole and rotate till you’re happy with the point. I know!!! Easy. It took me a bit to figure out. This unit is well worth the money.

Description not accurate
Do not buy this product if your lead is an artists lead for drawing. It has two gauge holes in the top into which you place lead as extended from the pencil. This shows you how far the lead should be extended from the pencil when placed in the sharpening hole. But these holes are small and accept only two small sizes of lead. Thus it is ineffective for sharpening thick lead. Any lead thicker than the lead you might find in some traditional mechincial pencils will not be properly sharpened by this device. Amazopn does not tell you that in the description.

I’ve never been so disappointed with any product ever
This product sucks. If you are looking for a sharpener for your 2mm lead with a reservoir look elsewhere. This will break your leads, every single one without failing. I cannot undersell how this product is just plain crap for a reputable brand. Please do not buy it or you will be disappointed. You will. Hey, you! You, reading this! Don’t buy this! This is crap!

I’ve never looked forward to sharpening my pencils before, but I weirdly do now
I never expected to write such an enthusiastic review of a pencil sharpener, but here I am! If you're wondering, "Is it worth the price tag?" the answer is yes—especially if you use a 2mm pencil regularly. It’s genuinely worth it. I want to clarify that I’m not sponsored or affiliated in any way; this is my honest opinion. To understand how to use it, you'll definitely want to check out the YouTube video on the subject though, as it’s definitely not self-explanatory and there are no instructions included in the box.
