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.
