      OK - But...

      Posted by Anonymous on 9th Aug 2014

      The machining work did not meet specifications. While the extrusion is of good quality, I paid additional for an area to be machined flat. "Surface error (flatness) to equal or better than farside (flat side) of extrusion stock." Two of the five pieces have significant tooling marks which I hopefully can lap-finish flat. The other three - I will have to have re-machined because of the significant surface ripples left by the machinist.

      Great product

      This heat sink will be used in a 2M linear amplifier and the heat sink forms the top of the enclosure. It looks great! Excellent machining and precise cuts.

      This is a great mid level heatsink and a very good value. I compared lots of other places and the heat sinks from Heatsink USA are well priced and ship very fast.
