Pros: Excellent Product. Plugged it in, installed drivers, and used it right away. Using Windows Vista Premium with no problems.
Cons: Once plugged in, you cannot plug in another USB device next to it due to space. Adapter is somewhat thick and takes up space, but that is just a minor thing.
Pros: Did a great job for what it was designed for.
Cons: Too long. It extended too far out. It broke when it was hit by someone.
Other Comments: Arrived as scheduled.
Pros: Works well, arrived promptly!
Other Comments: 64bit machines don't seem to like the drivers it comes with. I don't typically use it that way, just tried it out to see.
Pros: I discovered I needed a second of these adaptors. During class Tueday evening I placed the order. On Thursday afternoon it arrived in the mail. The old software can recognize COM ports 1-4; Windows 7 assigned it to 8; I changed the port and it functions with 1990's software beautifully. Quality product delivered very promptly (a normal execution of an order by Sewell).
Cons: No problems of the device.
Pros: Worked perfectly with Win 7 Pro 64 for an application where another adapter using the Prolific chip set did not work. The problem seems to be the drivers for the Prolific in Win 7 as it had worked with XP.
Cons: Costs more than adapters using the Prolific chipset. Would like it with an extension cable as it is bulky enough to block an adjacent usb port.
