pretty cool product

Product quality is low. I present only the attached image as evidence. One of the screw leads was manufactured correctly the other was not where instead of the cut across the top was off center. Edit 2019.05.27 - Upon writing my original review the business contacted me and indicated that they went back to the manufacturer asking them to review their quality procedure. They then indicated that they would send along, at no cost to me, a new set of anti-backlash nuts. The second picture is the new ones, which are in very good condition. I am therefore changing my review to 5 stars, simply for the fantastic customer service.

This is the 2nd one I've purchased that claimed to be 8mm lead 2mm pitch. Unlike the other one, this one worked perfectly and was actually 4 start. I bought them to go with this product: https://www.amazon.com/gp/product/B01FTTBLN6/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 Not trying to plug the product, but if that's what you bought then these should work.
