The quality of the product is excellent with machinery and finishing that match the level of precision necessary for wheel alignment! The kit is primarily designed to assist in measuring camber and caster accurately. I couldn't find my camber gauge at this moment (somewhere in my garage) and wasn't able to show it in the picture, but given the overall construction and beautiful finishing of the center adapter/plate, I am confident the gauge will attach to it precisely and nicely with the magnetic base.The product is mostly one piece in the box, and it took a few minutes to assemble the clamp with tire tread grips and pins to attach it to the wheel. Once you adjust it to fit the whee/tire size, the attachment is secure and fit. No play at all, which is important for your wheel alignment to be accurate. It is a huge help and gives me confidence in my camber (and caster) measurement where the wheel's center cap is not always flat to support this measurement; even when it is, the flat cap itself might not be aligned itself and can set off your numbers.This kit can certainly be used in a professional alignment shop, but it works in a DIY garage too. I have a separate method for precision toe alignment in a home garage and this kit is intended for camber and caster, which is very easy now with the tool.All in all, I really appreciate the premium quality of the product, its ease of assembly and attachment to the wheel, and the confidence it gives me in measuring camber and caster!
