Solid design, very easy to install the SSD (I got the bare version). And this is screaming fast. Zero effort getting it working with MacOS.I really don't like the fans in some enclosures - the make noise and can fail. If you have a drive with no moving parts what's the point of having an enclosure that has a moving part? Since this enclosure is essentially 100% heat sink it doesn't need one.It is somewhat larger than other enclosures that have similar functionality. But the overall design gives me more confidence in its reliability than others that I have seen and used. In my application it's sitting permanently on my desk so it never needs to go in my pocket anyway.Highly recommended.
