I homeschool my son, and can never find our pencil sharpener, lol. It is so aggravating. It’s something you end up taking for granted, and not thinking about, as you get older. I am pretty happy with this pencil sharpener overall. It sharpens very well, and they even include a spare core. This pencil sharpener can also run off of either 4 AA batteries or USB power. It does not hold a charge, though. You need to have it plugged in while in use. You could use an USB adapter, and leave it plugged in. The built in safety feature is also it’s one negative, that I could find. When you pull out the pencil shaving tray, it will not work. So, you couldn’t accidently hurt yourself with the sharpener. The negative part is, the tray is soooooooooo hard to remove. I had to get a jar gripper to help myself pull it open. At one point, I had to get my 21 year old son to open it. He is really strong too, and used the gripper as well. He laughed at it. The tray doesn’t have to be emptied all the time, fortunately, so I will continue to use this. I am assuming that it will loosen over time. The tray is transparent, so you can see when it needs to be emptied. You need to open it over a container, it is an open tray inside of it, and it will spill everywhere when opened. This unit is small and portable. It fits easily in a drawer as well. It sharpens both pencils and colored pencils perfectly, and to a nice, sharp point. The housing was done in a black and white plastic. It is pretty durable, and constructed well. On the underside you will find 1 long footing, and 2 small ones. These are non-slip feet, to help keep your sharpener in place while sharpening. These also work well. Overall, not too shabby.

I was afforded the opportunity to review BTSKY’s Portable Black Battery Operated and USB-powered Electric Pencil Sharpener for Watercolor Pencil, at a reduced cost, in exchange for an unbiased and honest review. This product arrives as shown.
