Pros: Got this for a system where we needed to run to projectors at the same time and split the display to make a huge screen. Works flawlessly, make sure you follow the instructions to a tee!

Cons: None, does what it promises.

Pros: Works great with voice/fax modems on my fax server. (Zoom) Driver install was painless and did not require a reboot, something nice in the windows world.

Cons: .... none, the hardware feels solid and works like a champ, I guess they could move the USB and Serial port on the front of the unit to the rear- but that concern is cosmetic.

Overall Review: A great overall product for adding serial ports to a newer system

Pros: This unit works great with the Altigen PBX- its one of the few devices in its price point that lets me select the dtmf transmission type... and has a spotless STUN implementation.

Cons: Cannot run two voice channels at once @ G711

Overall Review: To be honest I only needed one line for my application- but the big brother to this unit the SPA8000 works well too, its pretty much the exact same firmware- if you need more lines check it out.

Pros: Use these little guys all around the place- a great product with plenty of axises and a huge range of motion.

Cons: none

Pros: Got this for a floor man in our shop, he loves the lights- and its handling the grease and dust fine

Cons: none

Pros: Worked fine, had to install this on a Altigen PBX because there is no second onboard NIC- and I needed to dual home the box.

Cons: None, seems to be handling 20 remote voip extensions with high bandwidth codecs fine.

Overall Review: Looks Cool, granted a USB nic should be your last resort- it works pretty well.
