Pros: Bought to replace the 2gb in my Lenovo T60 and replace with this 4gb pair. Bottom line: a noticable performance improvement! I was always a little dissapointed with the speed of my Core2 T7600 IBM T60 with 2gb...just thought it should have been a LOT faster. Well - it is now! Don't know whether it is because I now have 3gb memory available (running XP Professional 32-bit) OR because the timings are indeed better (now 4-4-4-12-20)...maybe due to both reasons, but I am very pleased with the result! And, man, is good memory inexpensive these days!

Cons: None.

Overall Review: They look cool, too! Too bad there aren't many laptops with plastic windows to see inside...;)

Pros: Slick, inexpensive, and...it works!

Cons: You do need two (2) free USB ports - one for data, one for power (5 volts that comes off of the USB port. Kist does come with both cables needed.

Overall Review: Finally a simple, elegant solution to the problem of accessing data from old or replaced 2.5" laptop drives. This thing is truly cool.
