Review: My computer-illiterate 70 year old mother installed this herself without help. - My mother knows enough about computers to turn them on, search Google, and email links to cat videos. For anything else she usually calls for help, and sometimes I have to remote in using TeamViewer if that isn't enough. She recently moved to a new place that has wi-fi but her simple little desktop PC didn't have a WNIC. So I bought this and had it shipped to her, figuring worst case scenario she can return it, or hang onto it until I'm in her neck of the woods to install it. Well I called to ask if she got the package, fully expecting to walk her through removing the case, finding the available PCIE slot, screwing it in, installing drivers, etc. but nope. She decided to take a crack at it herself without ever having installed computer hardware of any sort in the past, and got herself up and running in no time. So yeah, it does its job and she's on the Internet again, and is super easy to install.
Review: Works better than advertised! - Product arrived on my doorstep, plugged it into a Gigabyte A320 motherboard running Linux Mint 20 (which is officially less than supported based on the product page) and it worked immediately. No extra driver installs or anything, just plug and play! That was nice as I was already gearing up to go driver hunting, but some research reveals the drivers for it are part of the Linux kernel, and have been for some time now. Low profile is good as I didn't have a lot of extra room left in the case, but it slotted right in without issue. Zero complaints!

### ⭐⭐⭐⭐ Performs mostly as advertised
*by Z***H on November 22, 2024*

Bought this for my desktop when I moved and didn't have access to ethernet for a time. Easy physical install into my case, and easy driver install. Mostly consistent wireless performance. Had some noticeable, but ultimately infrequent drops in performance. It did what it needed to.
