Hosmart Intercoms Wireless for Home UltraSpeak Pro, 2024 Full Duplex Wireless Intercom System for Business, Room to Room Intercom Two Way Real-time Intercom with 1200 Feet Range (3 Packs)

Works great, and set up couldn't be easier.I bought this to install a "plug-and-play" intercom system so I didn't have to yell at my kids from across the house anymore. It works exactly as I need it to. I started with just two, and bought two more for additional rooms - they all automatically connect as soon as you plug them in. I have them all linked so when you speak through one, it transmits through all of the others simultaneously, but you can program it to only transmit to a single unit at a time using a simple and easy channel system. (There are nine channel numbers, so my guess is that is the maximum number of units that can be linked together, but I haven't fact-checked that.) The sound quality on the transmission is great - clear and loud (which is great for children and the elderly). It has different settings where you can either transmit by holding a button down (like a walkie-talkie) or press an "on" button once that transmits continuously (like a telephone). What's more, all of this versatility is truly optional and not complicated. Like I said, you can just plug it in and it's ready to go, literally no set up required.They are built simple and compact, the size of a small book, are light-weight and their appearance doesn't stand out any more than any of our other electronic devices.The one possible down-side is that the material feels very light-weight, so it is possible that it might break easier than one would like. However, my kids have already (of course) thrown them around a bit and they held up fine. Also, even if they end up being more fragile than is ideal, they still are worth the very reasonable price.

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 addition for large house, it’s clear and easy to hear

Take them (2) out of the box. Easy Peasey. Works great. Consistantly working every night. The most easiest item I ever purchased on Amazon.

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! .

I bought these intercoms as my elderly parents had just moved into a larger house. My dad has limited mobility, and my mom was worried about being too far away from him in the house. We just set these up last week, and they are exactly what we needed in this situation. Using the intercoms is as simple as could be - you just hit the group call button, it rings the rest of the intercoms, and then from any of the other intercoms you can answer the call and start a conversation. It's clear when a call is active, and also really simple to end a call. My measure is really whether my elderly mom can learn how to do it, and she absolutely did.The intercoms also allow for a bit more complex functionality, like setting them on different channels and allowing 1:1 calls between intercoms. We don't need that for our use case, so I don't know how easy it is to set up. But for what we needed, these were perfect - easy to set up and learn, reliable, and the audio came through very clearly.

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.
