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.

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'm irritated! To save you time I am going to share the important things you must know about this intercom set. This is a dual mode intercom. It has a Duplex & Simplex setting. Duplex = Like a phone. Call, receiving unit rings, answer, talk like a cell phone, hang up. Simplex = Like a walkie talkie. Select channel, press a button while you speak, receiving unit broadcasts, let go of button, receiving unit must press button to respond. ** If you are wanting an intercom for a home residential use, DO NOT GET THIS! ** Here is why. Home intercoms should be Simplex only. In my specific usage, I only want to be able to locate and share information with another person or persons in our very large house. I am tired of yelling down the stairs for dinner, or to bring up laundry, or to ask a simple question. That is what intercoms in homes are used for 99% of the time. I don't need long two way conversations with someone in the basement. If that were the case, I would just go talk them. Commercial use may be different, and that's fine, this review is for residential use. This set uses both Duplex and Simplex modes. It has 6 channels. I set each unit to its own channel hoping I could label each channel to its corresponding room. After all, that is what an intercom is built for, right? Well, that doesn't really work with this set. Once the channels/rooms are set, you have to "call" a unit (duplex). That means the receiving unit's owner must get up, walk over to the intercom, answer the intercom, talk, then hang up. I could just walk half way down the stairs and yell "dinner" by the time I went through that. Plus, the recipient of the message has to stop what they are doing to answer a fricken call! This is not how intercoms should work in a home setting. So you may ask, just switch to Simplex, right? No. The Simplex is stupid. The calling unit must be on the same channel as the receiving unit. Ok, not a big deal, just memorize each room and its channel (or make an extension list, laminate it, and put it above each unit), no, again! Here is the problem. Once you select the channel you want to speak through, you press the "talk" button and it broadcasts on that receiving unit. But now the sending unit is on the receiving unit's channel. You have to then manually put it back on the sending unit's specific channel after you have finished whatever conversation. If you don't, well then whoever is trying to reach that unit/channel/room, is talking to themselves. Well guess what? Does this manufacturer honestly think that out of the 5 kids I have in the house that any of them are going to set their channel back to their corresponding room when they are finished "intercoming" another unit? Ha! So what you end up with is never knowing what channel the room you are trying to reach is on. Basically making this entire set a completely outrageous waste of time and money! So again, you may ask yourself, why not just make the kids use duplex only? They can select a unit (room) they want to talk to and make the "call" waiting for the recipient to answer and the adults can use the simplex version to announce household instructions. Sure, that is what I was going to do. Except...... The group function is also a complete waste of time. Isn't a group intercom function intended to deliver messages to all units? Kind of like a PA system. Not this one. Group communication DOES NOT work in simplex mode! It just rings all units and whichever unit "answers" the call is now in a private conversation with the sending unit!! Who designed this?! I mean seriously? Did the manufacturer ever even use their product to see how it works? See why I am irritated. Group means you are speaking to the... wait for it....GROUP! I have a very large house, 7 bedrooms. How am I supposed to inform all the kids dinner is ready? "push to talk" each room individually? Group call the whole house and hope somebody picks up, then equally hope that one child goes around and tells his or her siblings the message. Hope that when a child uses the push to talk they put the system back on its room's channel? Unbelievable!!!!!! If you want this for a home use scenario..... DON'T DO IT! It is a waste of time and money. Get this instead.... Find a "Half Duplex" or more accurately, a Simplex system with a channel lock. These systems make you choose a channel (room) to communicate with, then you "push to talk", that unit then broadcasts. Once you let go of the button, the receiving unit may "push to talk" and respond, or do nothing at all. Then after 60 seconds, the sending unit automatically returns to its default channel (room) and listens for another sending unit to speak to it. OH! and the group function actually works like a group function. Press "Group" an all units broadcast simultaneously. Most of these units also have a VOX feature which helps a Simplex system act like a Duplex system. All that is, is software that detects your voice and transmits without having to press the button. Its still simplex and only one person can talk at once, but it saves you constantly having to press the button to talk. In short, this kind of thing really bugs me. The listing is vague and uninformative. They waste people's time because they can't adequately describe what they are selling. And furthermore, I bet they never even use their own product. If they did, they would not design it the way its been designed. After these shortcomings, quality and price are irrelevant. This set has wasted more of my time than its worth and it is being boxed up and returned. In my opinion, this is NOT an intercom, Its an old 1990's cell phone.
