The name and description as well as the pictures show that this tool is capable of measuring all aspects of wheel alignment. It just isn't the case. This tool is for camber adjustment only. For this purpose the tool seems well made and works very well once you understand how to use it. So the problem is 1) can't be used for casters, 2) can't be used for socks, 3) comes without instructions, 4) the website listed in one of the reviews no longer exists, 5) needs to be investigated how to use it took longer than expected to get clear instructions. I'll be keeping the Camber Reader due to the price, but overall I'm not happy with how this device is viewed on Revain. I ordered a Tenhulzen Auto 3300 a few minutes ago to complete my hot rod.
