I bought 6 of these Reporter brand Wireless Intercoms and they are terrible. They will work well enough at first, to fool you into not returning them. Then later when you page another unit, they sometimes spit out some static but rarely can anyone understand a word. Sometimes they make no sound at all when another unit is paging. They have to 'form a network' and I think if they are unused for some time they form their own network of 1. I got rid of the Nova plug-in units and paid $300+ for these. This is the biggest ripoff since the Oldsmobile Diesels.

Extremely good buy,This item is so efficient and the voice comes out so clear.I took this intercom portable and walked a block and a half away and inside another building and the transmission was still clear.I use these intercoms to communicate with employees for price checks and to let the employee know when someone is stealing in our retail stores as we monitor the customers on security cameras.
good but for the money.

I purchased several of these on separate occasions and they all just stop working after a while with no damage done to any of the units. This may be the worst product I have ever purchased and as a business owner I do not recommend you wasting your money on these.

We started with one pair and loved them so much - no more yelling all over the house for the kids - that we quickly bought another pair. As some other reviews indicate, linking additional units to the first pair can be tricky. I'm pretty tech savvy but had to call tech support. Still had problems but after experimenting found that it is MUCH easier to link them up if you first set the dip-switch to the position that does NOT cause a secure conversation when one unit replies to another (see manual to understand what I'm saying). Turns out that when the units are set to go to the "private conversation mode" it either makes them harder to link OR makes you think the linking didn't work when you test them after the procedure. Still curious about battery life - so far so good after ~6 weeks but I'd just get the plug-in adaptor if they use batteries too quickly because we really like having these intercoms. The kids also love them - but make sure they know to talk normally and not to put their mouth right up to them when speaking to avoid distortion on the other end.

two upstairs and two down stairs. when you inicialy call someone on one of my four, the remaining three sound the words. whichever one of the three is used to reply back, cancels out the other remaining ones so they are not disruptive to others who might be in the rooms where the two not being used are located. You can also set one or more of these up to be voice activated so it could be used as a baby monitor or elderly person monitor. GREAT BUY
