Pros: Cheap Well Build Excellent Customer Service from Rosewill/Newegg I wrote a review before stating that the adapter would drop my downstream to 56k speeds seemingly at random even using the most recent drivers. A customer support rep replied to my review so I called Rosewills customer support line. I called at 2:30pm yesterday and around noon the next day they had shipped me a new replacement at no charge. No problems with this adapter so far after putting it through the paces a bit. I want to express how great of a job Rosewills customer support was, so here's 5 eggs.

Cons: None so far. Here's hoping everything keeps going smoothly.

Pros: It was decently priced.

Cons: Bought as a replacement for a HP Laptop that had a dead hard disk. Drive lasted for 4 months of very light use without being dropped or abused in anyway and then out of the blue I got a S.M.A.R.T. warning and the drive failed.

Pros: Fits great in my hand and has the perfect weight. Adjustable dpi on the fly. Just the right amount of buttons for me. Reliable. I've owned this model of mouse for close to ten years now. If you do have problems, you have Logitechs notoriously good customer support to fal back on. I've tried other mice, but I always come back to my mx518.

Cons: I had an issue with one of the rubber feet, but the mouse went through five years of heavy use.
