5.0 out of 5 stars | These things are godsends for conferencing
Color: Black
These things are godsends for conferencing. If you use Zoom, as we do, you can turn off the software anti-echo control in the meeting and allow the Spider's own anti-echo to manage the audio. The bump up in quality will be amazing. The beam forming mic array really does a great job of finding each person sitting at the table and making them heard clearly. Daisy chaining them works really well. Have used up to 3 in a string to make a big group meeting work in a web conference and each person could be heard perfectly clearly. This is truly a sophisticated and successful device. One quibble. The micro usb connection is fragile and has been known to break with rough handling. Have had to send a few back to Phoenix. They're good about it and say they're trying to harden them.

5.0 out of 5 stars | Amazing
Color: Black
I worked for a company that was utilizing these mics in the past but never really tested them myself. So I kind knew the quality of product I was getting. However, I wasn't prepared for the ease of integration. It was almost unsettling how easy this mic works with Zoom; as I was building a Zoom Room. There was some very minor frustration with the ceiling mount but that should be attributed to my own shortcomings not the device. We have 8 foot ceilings and it picks up nicely without issue. The speaker gives a full sound without distortion or anything. No calibration required. There's a dot that lights up indicating the direction of sound similar to an amazon echo. This is not by any means a stereo speaker meant for movies or gaming, but it works perfectly for the purpose it's suited for: audio conferencing. While it is a bit expensive regarding microphones, the piece of mind it gives warrants continued purchases as the need arises. If looking for a microphone/speaker specifically for audio/video conferencing this is it.

5.0 out of 5 stars | Great Unit, but even better Customer Support!!!!
Color: Black
This unit was requested for an specific project and its working even better than planned. Quality of Audio is Amazing, connectivity options are excellent and ease of use is one of the best features. The Application to set it up is simple, well designed and does the work is intended to without many complications. We had to request technical support for some of our specifics setting and environment, support was provided quickly and efficiently. Simply on our first install with unit, we think is the one to be using from now on, simply great.

5.0 out of 5 stars | Serves as great teleconference speaker
Color: Black
Loud and clear is what the speaker offers. It allows us to use it for our training video teleconferencing class that lasts over 3 hours. Everyone is able to hear us loud and clear and so can we. That's an A+ in our book and highly recommended.

5.0 out of 5 stars | Best solution for echo problems
Color: Black
Our office decided to buy this because we were having serious echoing issues when making conference calls. We are very happy we got it. It made a huge difference on the call quality. We definitely made the right decision getting it. It's very easy to use. The auto voice-level adjustment is the best feature.
