Product works as advertised. I have a Gigabyte X570-I-AORUS-PRO-WIFI-rev-10#kfItx board and had to remove the original heatsink to install it in the main nvme slot. Yes, the heatsink is bulky and the Gigabyte appears to have their own copper clad version that actually fits. Overheats and slows down without a case. So I bought this from Amazon: M.2 Copper Heatsink, m2 pcie NVMe Laptop Copper Heatsink with Silicone Thermal Pad, for M.2 2280 SSD Laptop. After installing this thing I get the speeds advertised, I didn't use rubber. strips and used the included thinner thermal pad. So either go my way or wait for the Gigabyte version (btw I think both use the same Phison SSD). Hope this helped you!
