Let me give you an example: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.
The answer to this example can be: Positive Review

OK. solve this:
Perfect addition to an enclosed ASIC/bitcoin mining server rack. The racks are already in a temperature controlled server farm and this A/C unit was the perfect solution for spot cooling! I liked it so much, I've since purchased another unit for a small room (10x10x8) and it even worked great for that. Decent on the CFM and since it's outside of the room, it's out of sight and out of mind. For a stand alone unit it is actually fairly quiet; quiet enough to not cause a distraction.
