@pzogel in the article the way the scroll wheel encoder is written of is a bit incoherent.
a) this mouse does have an encoder, while in the text you write that it does not have an encoder with steps. An encoder always has steps, as that is how they work. They may not have mechanical feedback, but that is a completely separate thing.
b) to my understanding, most mice have optical ones due to superior durability (edit: no they do not, mechanical are lighter, cheaper and more popular). Mechanical encoders are prone to wearing out very quickly. Other durable variants are magnetic encoders and capacitive ones, but i think that they cost more.
c) the encoder and having a mechanical contraption to produce mechanical feedback are usually more or less separate components, and you should not mix the two when trying to describe how the scroll wheel works.
Besides that detail, the article was very well written and interesting! Do you have plans of reviewing other ploopy products?
Edit: to my surprise kaihl encoders are mechanical. I might be wrong in how common mechanical and optical encoders are. Kaihl ones are rated only for a couple million scrolls :F
Logitech has optical encoders in some of their mice.
edited the post to fix the wrong info. Sry about that.
