Perfect for transaction windows.

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.

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.

The description claims this has super clear sound with no feedback. The manufacturer must have forgotten to remove the feedback from the one I bought. Horrible echo. The sound from the main unit, that comes out the external attachment, is so freaking choppy that our customers can only hear about every 3rd or 4th word we say.

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.

The system was easy to set-up and fairly easy to use but was broken after only 1 week of normal use.

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!!

Great for drive through
