Review on Wangdd22 Backlash Spring Elimination Threaded by Alex Taylor

First, they work as expected. The extra spring tension gives the lead screw enough resistance where my steppers won't rotate when not powered on. What I do not like. I bought it expecting to get two. It's my fault for not reading the fine print. However, for their cost, I expected a better end product as shown in the picture. The picture shows a nice shiny walnut without burrs. What I received had no burrs at all. Unchamfered holes, thread side chamfers, burrs pressed into threads, etc. For your money, go elsewhere. There is the same quality cheaper and offer 3 together. If I didn't already have it installed on my printer to see how it works I would return it.
