Review on ELUTENG M.2 to SATA Converter Adapter for Laptop Desktop - NGFF to 22-Pin SATA III Card Based Key B/B + M, Support 2280 2260 2242 2230mm SSD, Super Speed 6Gbps by Kevin Caldwell

I bought this unit to use as part of a test setup for M.2 devices of different lengths. The unit comes with a round clamp nut for 80mm units pre-installed and there are clamp nut holes for 30mm, 42mm or 60mm units. The kit comes with a round clamping nut that has to be soldered or glued into one of the open holes; not ideal for my purposes, but maybe acceptable for one-time use. The kit also included a clamp screw, small screwdriver and hex nut, the purpose of which is unclear.
