2 out of 5 eggsNot for 64 bit

Pros: Inexpensive, works OK on 32 bit XP

Cons: The device drivers will not install on my Dell M6600 with Win7 64 bit. StarTech support was helpful, but could not make it work.

4 out of 5 eggsWorks great fo rme

Pros: It is fast, takes little CPU, and does not crash my x201. Other USB to serial adapters blue screen the x201 without fail in windows and linux.

Cons: A little flimsy on the connector end, I need it a bit more rugged.

3 out of 5 eggsWonky

Pros: Seems to be working fine. This device is being used to collect data from a spirometry device that measures lung capacity.

Cons: Installed this adapter on a laptop with Windows 7 Home Premium. Included Win7 drivers did not work. Was able to force Win7 to accept XP drivers.
