5 out of 5 eggsAwesome Product, Works Great with Mac Air

Pros: Easy to use and worth the money. This is the best product to use when running on OSX (Apple MacBook), Super easy to use when running screen. Just plug in the device, open terminal and run screen. Thats it. Super easy and great.

Cons: None

Other Thoughts: It would be even better if the product came with a spare USB extension, But thats just getting picky. you can pick up and extension for 5 bucks off new egg.

5 out of 5 eggsAwesome

Pros: Plug and play on Windows 7/8, FreeBSD and my Linux systems I tried it work.

Drivers included on CD were older than the drivers provided by even Windows update, which is a good sign because that means Trendnet is still updating drivers for the device.

Speed test on the device gave me a full 5.8 Mbps

Decently long USB cable allows you to plug it in at the rear of a tower and have the serial port at the front

Cons: Doesn't make salad or something like that.

Honestly, there's none. The device is PnP on a good dozen operating systems and it works.

Other Thoughts: I should have bought 2

5 out of 5 eggsThe one to get! Best stock Windows driver support.

Pros: Plug and play no matter the version of Windows. It is very difficult to find that in this type of device.

Cons: I can't think of one. Reliable.

2 out of 5 eggsBaud Problems

Pros: It worked fine for serial mice

Cons: Assuming that it wasn't horribly mangling my 57600 baud connection wasted several hours.

The driver certainly didn't help dissuade me from this obviously flawed assumption; it even implied that it could handle higher bauds.

5 out of 5 eggsDoes exactly what I wanted it to!

Pros: Adds another serial port to a PC.
Works exactly like it's supposed to!

Cons: none

Other Thoughts: I bought this coverter to add a seconds serial port to my PC for troubleshooting networking equipment. I installed the XP drivers, plugged in the cable and both HyperTerminal and Putty work great with this cable. No problems at all. Yay! The cable I got was white, for those of you who are really expecting a blue one, just a FYI

5 out of 5 eggsWorks great with ESXi

Pros: Great solution to add a serial port to VMs running under VMWare EXSi 5. VMWare doesn't like add in serial port cards, but this works great.

Cons: None.

4 out of 5 eggsGreat

Pros: Been using one for years to program 2-way radios with no ill effects.

Cons: none that I have found in the 3 years I have been using one.

Other Thoughts: Had to buy a second one for a co-worker before he stole it from me.

1 out of 5 eggsAvoid - BSOD

Pros: Inexpensive, works out of the box.

Cons: BSODs. Using the device for the last 2 weeks on Win 7 x64, I have had two blue screens with high serial data loads, and one time during serial device reset. I have not 100% confirmed the USB driver was the cause; however, the blue screens occurred when interacting with the serial device and the PC has not had a BSOD in over a year.

Other Thoughts: I suspect the BSODs are dependent on serial errors and/or heavy load. Some serial devices might work fine. For example, when doing basic serial logging overnight; I have not had a problem.

5 out of 5 eggsperfect

Pros: Takes about 2 minutes to install drivers from CD. The adapter is then ready for use. Excellent Win 7 64 bit support, which is a deficit of some other comparable units. Good price break--all of these used to be $40 to $50 items.

Cons: No cons. Does its job flawlessly.

Other Thoughts: If you are tired of maintaining an old computer just to talk to old serial (9 pin) devices then this is for you.
