This is my first attempt at a video review! Apologized for the slightly crooked shot framing.

The Dahle 50 Fifty makes very little waste, so a newly sharpened pencil is almost as long as an unsharpened one.
The website I referred to was here, what seems to be a gallery of Dahle sharpeners, including some really cool midcentury modern cast iron models.
Summing up the video, here are some strengths:
- Tray fits into the base well
- Easily removeable blade for replacement
- Grinder chews up very little wood, to prolong the life of your pencil (see image to the right)
- Produces a short point, for easier control during writing
- Unlike a lot of rotary sharpeners, the exposed wood on the point is very smooth. No splinters or rough edges
- The adjustable barrel holder can hold oversized pencils, and guides them into the grinder, keeping the pencil straight
Some weaknesses:
- It’s rather awkward to extend the guide, open the hole, and insert the pencil with just two hands
- The shavings tray is loose, and rattles
- The whole unit is plastic and feels cheap
- Mounts to the wall or a table with a Command Strip, which might be knocked loose during sharpening a particularly hearty pencil
Overall, I give this pencil sharpener 4 stars out of 5 — I will enjoy using it because of the great point it creates, with a minimum of waste.
As I said in the video, leave a comment if you find somewhere that sells this model!
