Incredibly comfortable to use. Good features and works clockwise on all substrates I tested it on. Battery life about 30 hours of use. NOTE, this is a rather old copy.
It has some great MEN. The solutions should not be made if there is a guarantee left. At your own risk, etc. But it should not be needed on a mouse in this price range. Hence 4 stars, barely approved.
- The scroll wheel works poorly. Scrolls in all directions except what you want.
The rotation sensor in my name is "Kailh 9". Rumor has it that fat penetrates into it. I managed to get it in order with 5-56, it dissolves grease, lubricates and is good for electrical contact.
- The scroll button stopped working, the contact plate itself in the connector was worn.
Switched the contact plate to a plate in another mouse I had lying down.
