Pros: cheap 4.99, decent capacity for price from newegg shell shocker

Cons: not the fastest, but what can you expect from usb 2.0 instead of 3.0 gen 1 or gen 2 kind of physically large compared to others, but got cheap from newegg shell shocker

Overall Review: retractable end seems to wear after a while, shinny plastic is a finger print magnet, USB 2.0 is kind of slow for install compared to 3.0 but cheap from newegg shell shocker bought 5, all still work after several rufus re-images, not really fast enough as a bootable OS as ultra fit, but then again it's 1/6th the price and 1/8th the capacity.

Pros: one button to switch DPI, and double fire button. The blue led is bright compared to red led (not really a pro)

Cons: Scroll wheel feels fine for first 20~30 pages then will go the opposite direction. about every 2 scrolls it will scroll opposite direction. The base of the mouse will pop to the side like the molding of the top and the base are not the same size. The mouse button 6 and 7 are reversed from most 7 button mice, so back is tip of thumb instead of base. The mouse also started to give off an odd smell when the scroll wheel started messing up. The sticker for the rubber the thumb feels loose.

Overall Review: I purchased this to replace an ocz OCZMSEQRM that I purchased from here in 2009. I wish I would have read more reviews before blindly buying into a brand that I used to trust. Being that this mouse was 19.99 and reduced to 11.99 on Jan 13 2012 I can see why it would be worth over 5. It is not worth 5 bucks and paying anything to ship back something defective wouldn't make any sense considering whats even worth recovering or even salvaging from such a small piece. Contacted Newegg support today and said it was longer then 30 days from purchase event though I had it possession less then three weeks DHL drop to UPSP. :( with a cheaply made product and the customer service provided with I could give 0 eggs.

Pros: Performs everything as claimed. even counts kwh on < 1 watt over time

Cons: lcd hard to read some times, and if you unplug it, it doesn't remember what kwh's have been used like other units i've used.

Overall Review: my 2 quad dual gpu gaming rigs use between 260~1500 watts :( (that including lcd's and 6.1 surround sound)

Pros: 200 burnt @ 16x no coasters

Cons: edges of discs are a lil rough but hey their cheap
