★★★★★Compatible with Legion Go 1
With an adapter this was installed into a Lenovo Legion Go 1 and has been in use for almost a year now. The speed and heat of this NVMe SSD is perfect for my unit. Remember the Legion Go requires a 2242 so you WILL NEED AN ADAPTER for it to install properly.

★★★★★Great buy.
Great storage card! It was easy to install, it works well, and is very fast as far a uploading and downloading are concerned. Four times what I had before. Thank you Best Buy for the great product, and the fair price.

★★★★★Excellent 2TB M.2 drive in 2230 form factor
What more needs to be said. This is a small form factor M.2 drive, very useful for devices that need the smaller factor (many handhelds, tablets, and even some smaller laptops can only take the 2230 factor). Typical WD Black quality, which is excellent. The drive can get a bit hot, but that's the same with any drive of this capacity and size (really, most M.2 drives can get pretty toasty anyway).
