Pros: By far the most comfortable mouse I've ever owned.

Cons: Didn't track well on black mousepad, after doing some research found it's a common problem. Still has occasional tracking issues on white pad. LMB has stopped working correctly. Sometimes fails to recognize clicks at all, sometimes doubles up (ie reads 1 click as 2). Incredibly annoying, especially on pull downs (will open an close very quickly).

Overall Review: After years of rocking my Logitech MX 518 the scroll wheel died and instead of trying to find another one (discontinued) I decided to try something new. After reading multiple reviews I finally decided to give the RAT 7 a try and picked it up on sale. It's super comfortable but other than that I can't say anything good about it. Absolutely not worth buying and the experience has been so frustrating I highly recommend avoiding this brand.

Pros: Quiet, good storage (1 TB).

Cons: Didn't work properly from day 1, seems to suffer from firmware corruption issue common in older Barracuda drives. SeaTools to diagnose HD wouldn't even detect drive.

Overall Review: So I have always used another brand's externals but after one of them failed I decided I'd give Seagate a try. Based on my experience thus far, this will be my last Seagate product. From Day 1, the drive would intermittently drop connection to my computer, annoying but not the end of the world. However, as time progressed, the HD started becoming randomly inaccessible and disappearing entirely from under My Computer. It miserably failed a Check Disk and I wound up having to reformat, hoping that was the end of the problems, it wasn't. About 2 weeks later, the drive started down the same path. At this point, I started digging into known issues with the drive and the issue sounded similar to firmware issues from the Barracuda 7200.11 HDs. I contacted customer support, went through 2 e-mails of testing/troubleshooting to no avail. I have 2 other external HDs from another manufacturer that currently work perfectly fine in all USB ports and tested the Seagate external using their USB cables and still have the same issue (as well as having the same issues with the Seagate external on 2 other computers). Will be returning the drive today, will see how Seagate responds.
