We've had great success using this with ConferenceXP. The audio quality is quite good, the AEC is great, and the AGC is excellent. I don't know how well the daisy-chaining works, though, so hopefully someone else can jump in with that.
The output from the mic is a little high, though, so make sure you have a good sound card that doesn't distort easily (anything other than bottom-of-the-barrel is probably sufficient). I heard that they've updated the firmware on these recently, and the new ones work even better. But just to keep things interesting, there's been a thread on the CXP mailing lists about the new super-cheap contenders in this arena, and there are apparently a number of them: >>> "Chris Moffatt" <chris...@microsoft.com> 11/09/05 9:16 AM >>> If you are tired of using a headset for Conferencing, but don't want to shell out $100's for an echo-cancelling mic...the miniVox MV100 is a great little echo-cancelling mic that works great for desktop conferencing. (http://www.mvox.com/mv100.html). It is a USB device that doesn't require any drivers - just plug and play (er talk). I have tested it with ConferenceXP, and it works great, and have heard the same from a number of other people. >>> Jonathan Tregear [jtreg...@salud.unm.edu] 11/26/05 12:47 AM >>> The miniVox is the best deal at $20, but if Sharper Image stops selling it at that price (it lists for $40) then the VoSKY Chatterbox at $30 is better: http://www.vosky.com/product.php?pid=8 It also has DSP enhanced full duplex (probably the same internals) and also has Volume Up, Volume Down, and Microphone Mute keys, which the miniVox doesn't have.

At least one of these will be in a small conference room. They are understandably hesitant to invest in a $3000 Clearone (formerly Gentner) echo canceller (XAP400), and have pointed out an interesting echo-cancelling microphone, the ClearOne "AccuMic PC Desktop Echo-Cancelling Microphone", viewable at: http://mcsnetzone.com/clmifa.html I'd feel happier about advising the purchase of this $600 unit if I could talk to one or more folks who have used it successfully in an AG setup. Does anyone out there have experience with this unit? If so, I'd be delighted to hear from you...
