I use it everyday! Review: Good quality - Accuracy that is almost perfect, and good enough for almost any use. I love the digital readout and the fact that it can be oriented in any direction. It's easy to read. I think it's necessary for me to monitor my own progress with physical therapy after knee surgery. BUT---one would think that the company would benefit from getting someone who can write with proper English grammar and sentence structure so the directions make sense. It's a small instruction sheet but go figure what they are trying to say. That is my only disappointment with the product. It might as well be written entirely in Chinese! ## Features - 【New Buttons】Different colors acheive different functions. Easier to use and remember. - 【Improved Function】Press WHITE button once to reset zero degree. It's convenient for measuring different joints. *Old version need to press for 2 seconds to reset zero degree. - 【Invert Display】When measuring on awkward position, click RED button to inverted display.
