Pros: This mouse is an all around winner. It has an excellent battery life. I can go 4-8 months on 2 batteries and I use this mouse for 8 hours a day, and never turn off the switch at the bottom. Also, it is extremely accurate and quick. The "infinity" scroll wheel is great. If you are like me, you will spin it like the wheel of fortune wheel then hit the wheel lock and hear it buzz to a stop. I have ADD though, so you may not do that. I have a big hand and it still feels comfortable. the buttons are all well placed and the clicks feel nice. I have one at home and one at the office. Whenever a co-worker's mouse breaks in my office, this is the replacement I order. Everyone loves this mouse in the office.

Cons: The only thing I am not the biggest fan of is the secret thumb button. it will pull up all your running programs if you have the Logitech software installed, but it doesn't hit a "real button" so when gaming, if you want to map it to "Crouch" you first have to reassign the button to a key combination, then use that combination in your game's key bindings. every other button will report as "mouse1" ore "mouse2" Also, "Mouse3" which is usually pushing down on the scroll wheel seems froggy when gaming. I eneded up dropping mouse3 from all games.

Pros: Looks Cool

Cons: The touch controls on this thing are dismal to say the least. It should have it's own usb interface so you can control it via a desktop app.

Pros: None

Cons: 4 drives were ordered to throw in a Sata/SAS JBOD. One drive was DOA, one drive Failed at format, one drive failed during data migration. Right now we are down to one drive, taking them all back. This is ridiculous. Who makes drives that fail that quickly?

Overall Review: I am going to try the HGST drives and see if they are any better, I know it is now Western Digital, but I hope they kept the NAS manufacturing plant.

Pros: Fast

Cons: I have replaced more of these then the old 40GB maxtor drives a decade ago. The worst SSD on the market. Unreliable. When you send one back, they secure erase it thinking that fixes it. It doesn't, ever. Then you are forced to have an unstable drive that still had bad sectors, they just shave a few more gigs off of the total drive size and say it's fine. It's not. It sucks.
