Pros: Works fine.
Cons: Even though your site said that this product supported Windows 7 64 bit, the CD provided did not mention it nor did it have the drivers for this my OS. Had me worried and wasted my time to download the drivers from your site. This was lazy on the part of Sewell. You should at least have put in a note in packaging to this scenario.
Pros: These are inexpensive and work great. Every one we've used has been simple to install and flawless in operation. For business oriented (non-video) use, the display quality and response is indistinguishable from displays connected to physical video cards. With 1 or 2 of these on a 32 bit system or up to 6 on a 64 bit system, we've seen no problems with memory, system performance or anything else.
Cons: We were unable to get 4 of them to work at the same time on a customer's 32 bit Win7 PC. Initial screen display worked ok, but as the customer ran things that changed what was displayed, all kinds of quirky things started happening and the displays got all messed up. We suspected some sort of memory issue, so we switched to 64bit Win7, and have not had a problem since.
Also, they are not at all useful for streaming images like NetFlix or Hulu. The sound keeps going but the video stalls out.
Other Comments: I have been using 1 of these for about a year on my personal system and got a second a couple months ago. The system they're on (64bit Win7) also has 4 other monitors connected to physical video cards. No problems. As a stress test for a customer, we tried connecting all 6 monitors using Sewell USB adapters for about a day. Again, no problems whatsoever for still images. We have installed 5 of these on customer computers, have no problems and would not hesitate to install more.
Pros: Easy setup. The Minideck drives a 23" monitor via a 25' SVGA cable. Monitor is mounted next to my office meeting table. Added a wireless keyboard and mouse, I can now do meeting presentations easily.
Cons: Setup from CD didn't work. Had to go to the website to download WIN7 x64 drivers, but that was no big deal.
Pros: original had problems freezing and cutting out. Had it replaced and performance is much better and has cut out only two or three times to far.
Cons: occasional freeze
Pros: Dead simple to set up. Works exactly the way you expect it to.
Other Comments: With multiple monitors on Windows, you'll probably want a couple of freeware programs to upgrade Windows multi-monitor capabilities. I would suggest UltraMon and WinSplit Revolution (I have no connection with either program).
