Pros
It is easy to operate and therefore can be used by both adults and children effortlessly.
You can be able to tell when the reservoir needs emptying since it is transparent.
It takes up very little desk space thanks to its small dimensions.
The auto stop feature prevents any over-sharpening and injuries when your child inserts a finger into the sharpener.
It is very light and portable.
Cons
Its small size makes it very unstable so you have to hold it during sharpening for stability.
