Pros: Really fast shipping, exceptional read/write speeds, solid performer. 5th drive by this manufacturer, and all working exceptionally well in production.

Cons: Would be nice if cloning software was included with the drives, but Macrium Reflect Free does a nice job.

Overall Review: Overall, would recommend these drives as a cost effective upgrade for any of your network workstations of mobile workstations.

Pros: Sharp "looking" mouse. That's about it.

Cons: Mouse "feels" light and just low quality. Connectivity with the wireless receiver is very poor, even from less than 2 feet away. Mouse buttons started to lose elasticity almost immediately, IE: the left click button's range of motion (click) degraded after only an hour of work in an engineering/CAD environment. Single click produced double-click within an hour of use. Turning the mouse off and back on corrected the issue for less than 30 minutes before it returned. Perhaps this one was a lemon, but we will not be purchasing another and highly recommend Newegg.com remove this item from their offerings. Been buying from newegg for more than ten years and this mouse is not the quailty that we have become accustom to... at ALL. This purchase was to test the quality of a new standard of mouse (without horizontal scroll) for our engineering department, and the mouse itself was very inexpensive, it failed miserably. In this case, inexpensive = CHEAP.

Pros: Very well packaged. High quality unit, with thick cable and solid construction. I'm the IT manager at a Mechanical Engineering firm and can say with confidence that this product designed and manufactured well.

Cons: No cons.

Overall Review: Great product! I'll buy more when needed, without question.

Pros: Precision 5520 connectivity, 2x HD monitors and the laptop screen, several peripherals plugged in and all are working flawlessly. Was back and forth between this unit, and the "current" version of the same unit for $100+ more. Glad I went the route I did. Everything works great and without ANY hiccups.

Cons: None.

Overall Review: I am the IT manager for a CAD Mechanical Engineering company, and I am comfortable recommending this product. If you're on the fence, don't be. This unit will do what you require.

Pros: Fit's nicely in your hand, programmable buttons, center-click (wheel button) button functionality lasts more than a year. Previous standard (M310) center click button would start flaking out after less than 1 year.

Cons: Have found ZERO cons.

Pros: Easy setup, great graphics, good backlight and crisp display.

Cons: None

Purchased 4x of these units to give them a try because the price was so affordable and because I've used the brand before. Surge protectors arrived quickly from out of country, and look and feel to be good quality.

Marketplace seller, shipping from USA. Good external floppy drive.

I use these in our office for the dual monitor setups of my Engineers. They're relatively easy to assemble, come with some cable routing, and are very sturdy. Would (and will) purchase again.
