Perfect

Pros: -Perfect clearance for raspberry pi cluster -Nice, quality feel -As advertised
Overall Review: I especially recommend this for those who are building a raspberry pi cluster. It fits perfectly in those acrylic stackers.
Not so great.

Pros: - Linux Compatible (kinda). - Cheap.
Cons: - SLOW. Downloading a 1.5GB tar archive off my server took about 6 hours, at speeds always less than even 1MB/sec. They usually average a luke-warm 80KB/sec. - Cannot handle a lot of traffic at once. If downloading/uploading a file to the machine, even opening an SSH tunnel takes time, or any other tasks the machine is running will become seriously throttled or even disconnect. - NO dual band. does not support connecting to 5GHz networks. - The card doesn't even turn on every time the computer boots.
Overall Review: - I don't recommend this product for heavy use. or server use. (I bought this for linux compatibility). - If you have a low-end office desktop for checking email and other light browsing, this may be for you. - Gamers, keep looking.
Solid shelf, hard to adjust

Pros: - This shelf holds the weight of my equipment at full extension just fine.
Cons: - was packaged poorly. The part where my rack bolts go was severely bent, and I had to bend it back before installing it. - the nuts on the side rails were way too tight, so it was difficult to adjust the rail length. Required tools. - shelf doesn't lock, so if you try to push cables into your equipment from the back, the rack will slide out if you don't hold onto the shelf.
Overall Review: It gets the job done once fixing the damage and getting the rails to the right size.
Great fit

Pros: - Snapped Into my Tripp lite blank patch panel perfectly. - I don't see any reduction in speed on my network. - no punching down cable.
Overall Review: Fits the need perfectly.
Linux support!!

Pros: - This is not officially supported on Linux by TP Link, However if you're on a debian-based machine, the package "broadcom-sta-dkms" will get you going with this. - I bought this after buying another TP Link card: this one runs circles around it. The server it's connected to (wireless for now, unfortunately), can now handle more than one peer, and Samba/rsync/file flinging isn't painful. This fixed 100% of the problems I was having. - 5GHz channel!
Overall Review: - I recommend this product, for sure. It's very responsive, and if you're a linux user, hop on board and use a quality card for desktop! Its worth the few extra dollars.
Price gouging
Sold me a cooler for more than double the actual price than these go for.
exceptional customer service
I ordered a part that I knew in the back of my mind to be new old stock, and didn't have high hopes of it working as intended. It's not the seller's fault, but I was really hunting for this item. When the product didn't work, they didn't ever hesitate to keep in touch, and eventually offer a replacement or a refund. They didn't even make me return the defective item, which would've been a hassle for both of us, especially since the item didn't work to begin with. (I recycled the part.) I bought this same item from another seller, and those folks tried as hard as they could to deny a refund. Betech Parts didn't. Very pleasant to work with.
