this is fantastic and will be worth the premium for those who can't buy an enclosure and do it themselves for less money. but for me, as i keep an eye on enclosures, it is not cost effective. you can buy an NVME enclosure under $35, or a TB3 NVME enclosure for $75 a key selling point for the Crucial is the "ruggedization", round corners, and plug n' play. but all of my M.2 enclosures ( i have 3) are heatsinked with a machined chassis (cuz i'm that guy) BUT are square cornered making it not great for shirt pockets. which is ok i keep it in my pants 😀:D 😱 😱o_O
