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

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.

Wasn't expecting much for the price, but these turned out to be a pretty nice set of intercoms. Voices are clear, and the quality of the units is good. Each unit comes with it's own cord and power block, so I am very happy with that. We have a large house, so I ordered a set of 4, but you can get 2, 4, or 6 units and assign each one a station. Set-up was as easy as plugging each unit in and assigning each one a number by pressing that number on the keypad. Okay, I've read some poor reviews that I would like to address now. 1. These ARE Dual VOX. The trick is to assign each unit a number by pressing and holding a different number for each unit. When you talk, press the number of the unit you want to talk through, and then wait for someone to pick up. For example, if you are at station #1 and want to speak to someone at station #2, press the button with the "2" on it, and then wait for someone to press the "talk" button. You can then talk easily without pushing the talk button. 2. Voices are clear when speaking, but keep in mind that these are VOX units, and there is a slight delay when speaking, so wait a second before responding. 3. The "MONITORED" feature is NOT for having a conversation. Watch the video in the Amazon description for more information about other functions of these intercoms.

good working product but we're still trying to get it working. Its a slow learning experience for an 88 yr old. Gets very frustrating. It could use step by step instructions. Other than that it appears to be well worth the money.

These are fantastic. Full duplex, hands free talking. For those reviews stating they are not full duplex, they are certainly mistaken and not using the correctly. These intercom units look nicer than so many other out there too. Crystal clear and they are perfect to put in my office, kids rooms, etc. so nobody needs to yell to communicate. Highly recommended, took no time at all to plum them in and start using them. Virtually 1 button to set them up and assign a different number to each unit. Better price than other 4-packs as well.

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.

Having problems with interference on certain channels, 2 of 6 seem to have problems with interference. The other 4 channels are clear and work fine.

I had previous intercoms but those were too difficult to program...these are so easy...basically just plug in and they are ready to go.....You cannot go wrong by ordering the Hosmart UltraSpeak Pro Intercoms.

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.
