Review on Thunderbolt 3 Dual-Slot M.2 NVMe SSD Enclosure with Thunderbolt 2 Compatibility for New M1 CPU by John Lewis

Clean device. Compact. It gets very hot even when idling. Seems to be idling at around 46C with a Sabrent 3.0 2TB NVMe. With a constant load, 62C work. Doesn't overheat but feels quite hot. Luckily I found another case with the same PCB but with a different 4 digit number that runs significantly cooler (54C) under load. It could just be a bigger, heavier aluminum case with more surface area to help it run a little cooler. Installation is easy. The screw holes aren't very smooth or hidden enough so it doesn't lay perfectly flat without scratching what you installed it on. The case sticks out a bit due to the necessary NVMe heat-conducting foil. The speed is great. Can be used as a startup disk on the iMac. Very compact.
