Pros: This phone came to me in factory packaging. It could have been a new phone - the only thing that gave it away was a tiny nick on the chrome frame near the earbud jack. No other scratches anywhere. I transferred the contents of my S4 and then pulled the SIM card and moved it to this phone. Seamless switchover.

Cons: I should have bought more than one!

Overall Review: I am always wary of used electronics and look at seller ratings when deciding to buy. There were some complaints of dead phones and long delivery times, but mine came in 2 days and I had it on and operational on the 3rd day.

Pros: Replaced SATA drive in Dell Precision M4300 Laptop. It was a huge leap in performance. Very fast, quick boot up times.

Cons: Only lasted 4 months and suddenly died. Computer does not see it. Tried in another PC, same thing. Replaced it with another SSD (SanDisk Extreme), which I originally had other plans for.

Overall Review: Sleep mode killed it? I've been reading about that. I assume SanDisk will replace it, currently awaiting RMA.

Pros: It fit the PCI-E slot

Cons: Card is recognized, but the setup process involves running an .exe program on the supplied CD to get the drivers. That takes a while. Then, the computer sees the card as active and no problems but as soon as you plug something into it (even a Thumb Drive), you get a "Device overload" error message. Nothing that I plugged into it worked.

Overall Review: It was cheap, so I didn't lose much money. Deciding on whether to return it or not.

Pros: Lived in my pocket for 3 years. Endured rain, snow, heat, cold, at least one trip through the washer, and a lot of use.

Cons: It died after 3 years despite the tender loving care that I gave it.

Overall Review: Transcend is sending me another one for free since they have a lifetime warranty.

Pros: For the price, you can't beat it. In everyday use, with all other components of the PC being the same, it will perform on the level of Intel's Core i5, which costs more than twice as much.

Cons: Haven't come up with any negatives.

Overall Review: My main Home PC is an original Core i5. My office PC has the X3 in it. I see very little performance difference between the two very different computers.

Pros: I never thought I'd get that much light from one AA battery. I've used it a lot over the past 5 months and still am on the original battery.

Cons: None
