Review on 🐭 ELECOM Handheld 2.4GHz Wireless Thumb-Operated Trackball Mouse: Smooth Tracking, 10-Button Function, Precision Optical Sensor - Left/Right Handed (M-RT1DRBK) by Cody Johnson

Judging by the photos of the product it looks like an innovative design for mobile and stationary use and I don't expect high quality materials from Logitech products. My assumptions were only half right: cheap quality plastic, but the good expectation was wrong: its stand just can't keep the product in place for stationary use, even at an unergonomic height for a medium-sized wrist. And these 10 buttons. not really configurable, even with their "latest" (2009) utility app downloaded from the manufacturer's website. For a price of over 70€ this product is absolutely not worth it in my opinion.
