Works great! We are able to hear through the glass in our office much better. Delivered quickly, no issues so far.

I like the fact it’s a power unit, not battery. It is very easy to set up and use and it’s nice that I can carry on a conversation through a window without having to yell. The only bad thing is my situation requires me to change locations so I can’t stick the outside microphone portion to the window.

You can’t even hear at all sometimes as the voice cuts and it sounds too far 🫤

We have brought two of these. We use them on our food truck the first one got wet. They work good. It’s just the generator overpowering at times

This was a real easy, out-of-the-box set-up and use device. It works as expected and the only reason it didn't get 5 stars is: in order to hear the other side, the volume level inside with the microphones and speaker close together, (only separated by glass,) there tends to be a slight buzzing sound. Not overly bad and I may be nit-picking for perfection but this is an honest review and if I needed a second one, I would buy this same model again because it works well.

Perfect for transaction windows.

I needed an intercom solution that would go a long distance over wires. Performance is exactly the same when plugged in directly vs using a 100 foot extension.

Since Covid caused us to plexiglass our registration window it was very difficult to communicate with our patients. This has been wonderful I helping us interact with our patients!!
