Hosmart UltraSpeak Pro Intercoms Wireless for Home, Two-Way Real-time Intercom Full Duplex Wireless Intercom System for Home Use, Clear Sound House Intercom System for Business with 1200 Feet Range

It works. Don’t ask me how to set it up. I let my 12 and 13 year olds work that magic and they did. They’ve also proceeded to tattle on their older brother and make creepy demogorgon sounds for the last 30 minutes. There’s been no issues with me be able to hear any of that nonsense, so at this point five out of five stars for functionality.

The intercom works very well. The voice is legible??/audible even between floors. And the operation of same is quite simple--even senior citizens can figure it out. Good product so far and it has a 24 month warranty.

I have installed intercoms in several rooms of the house, both upstairs and downstairs.We are absolutely thrilled with the operation, and as they are portable, I can move the unit to the garage and still keep in touch. They are compact and simple to set up. I highly recommend them.

Great product but could be louder

Pleasantly surprised by quality and effectiveness!

I bought one of these to be used in in our house with children, as it sometimes is difficult to call from one floor to the other. However, the model we bought - although crystal clear- was not loud enough. Probably perfect for office use or for seniors. reached out to customer service, who advised me about a louder model HY811. got it, and it works much better! Customer service was great! .

Awesome speak listen device, my Parents and I all live under one big roof a shared home.They are both 68 and in a large home its hard to communicate easily, So getting 4 of these to place in and around the home was ideal for us.All I can say is it works and my Parents are much happier.

These units are not Full Duplex, they are Half Duplex with VOX.Both users cannot talk at the same time, If you attempt to talk while the other party is already talking then you will not be heard. One of the units I was using was in a loud environment and it stayed keyed up all the time. The 2nd unit could never talk to the 1st.I did follow the directions in the instructions and put the 1st unit on channel 1 and the 2nd on channel 2, pressed the #1 button from unit 2, the user on unit 1 pressed the answer button, VOX worked fine, but VOX isn't what it say on the package, it says FULL DUPLEX. So both users cannot talk at the same time. Changed the channel to 3, 4, 5 and 6 on the 2nd unit while unit 1 stayed on channel 1 and the results were the same. We then reversed the order and on unit 1 we changed the channels from 2 to 6 while unit 2 stayed on channel 1 with no difference.If you purchase these units knowing that they are Half Duplex with VOX then they are very good. They work as advertised and sound clear. NOTE: I only had the units about 30 ft from each other for testing purposes, they were transmitting through 3 walls with electric and WIFI all around them.The issue is that it says on the box that they are Full Duplex and they are not. Because one of the locations is in a room with a loud TV and a window unit that is a bit noisy then the compressor is active it stays keyed up all the time and the 2nd unit can never talk to it. So they will not work for my intended purposes. I am returning them.
