Easy and effective
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.

A cost-effective room-to-room communication
Great product. Good sound. Easy to install or move if needed. Will be adding more units to connect more rooms.

Cheap and Good
I pretty much got tired of hearing people yelling from downstairs in my house like Neanderthals so I wanted a cheap and effective tool to talk to people from room to room efficiently. I even thought about getting a professional and permanent system installed, but I decided it wasn't that serious. These were way easy. All I had to do was literally just plug them up and just long press which number I want to assign to each room and its done. Also, long press the talk/call button so it go to auto answer (so the receiving end does not have to touch it to allow you to start talking). Easy peasy lemon squeasy. I have four bedrooms, so I put one in each room, then I put one downstairs next to the kitchen table and one in the upstairs family room and its all good. Now.....if we could just break the habit of yelling around the house then we would be all good. But the intercom system works great.

Pretty nice for home use
I really like these devices. They're small and very lightweight (they seem to consist of just a PC board and a speaker). Sound quality is really good. There's no battery option, but that would increase the size and weight. You can pick one of 6 channels if you want to be able to call a specific unit. Example: channel 1 for the kitchen, 2 for bedroom #1, 3 for bedroom #2, 4 for the garage, etc. Alternately, assign the same channel to all units so when you call, they all ring and the other person can answer wherever they are. You can monitor a room without being heard. My favorite feature is the two way communication. You can call another room, and when someone answers, you both can talk at the same time. It basically works as a speakerphone! It's better than VOX because unlike VOX, it does not cut out the first word (it does not have VOX). What I don't like is the sound volume. If someone is hard of hearing, they might have trouble. That's why I removed one star.

Easy to use and good sound
This intercom works well. We use it from the house to the back unattached garage. Easy to get started, just plug them in and choose a channel. Good price for the set of 2. They are much smaller than the picture looks like which is nice.

👍
We use this extensively for my house; they work extremely well. I wish that you could have the ability to dynamically switch different channels on the fly. You can't, but it's just more of a user thing than anything else. They work, they sound good, and they don't emit weird sounds that you get sometimes with devices like this. Audio is really good. They get loud, and the microphone is actually very good. For something like this, I recommend it.

wireless intercom
The price can't be beat. Small and compact to locate in small area and not be noticed for anyone to play with. The sound isn't the greatest, best it does the trick. It doesn't go through our house and metal pole barn as clear as we expected. The distance in ONLY about 100 feet, so I'm guessing the building material is what is not letting the intercom perform at its optimum capacity. Again, the price can't be beat and it does work, just not as clear as our old one.

This is an excellent product. It's easy to configure and compact making it a non-intrusive item for the study desk or kitchen bench etc.
