    I purchased this for a DIY CNC project machine. It arrived faster then anticipated and the packaging was very nicely done. I haven't used the product yet but close inspection gives away that it surpasses similar products via. Amazon. This is one of many I need.

    really nicely machined

    I wanted to replace the stock couplers on my CR10s, these were recommended on a vlog I watch as being good quality. I'm very happy with them. They're more flexible that the stock ones and they are beautifully machined. Happy with my purchase.

    Needed an 8mm to 8mm coupler but was not able to grt one quickly. Got this one and drilled out the smaller side. Works great
