SUMMARY: These are the best wireless intercoms I have ever used. They are not perfect, but they are very good. With just a few tweaks (outlined below) this design could be improved to create the perfect wireless intercom system. I don't regret this purchase at all. I would buy this system again as I expect to get a lot of use out of it before something better comes along. However I still feel that I need to keep my eye out for an even better system that is truly worthy of 5 stars.=========THE GOOD:=========+ RANGE: I have 5 of these scattered around a 2 story home. Range is not an issue through multiple walls (drywall construction) and a ceiling. The manufacturer claims 1000' range which seems reasonable given the performance I am seeing in my home.+ INTERFERENCE FREE: These use 900MHz radios which is no longer a popular frequency for consumer electronics leading the less interference. I have not noticed any static or other interference issues with my dual band 802.11n 2.4GHz/5GHz router, any of my 2.4GHz bluetooth headsets, my microwave oven, etc. My DECT 6.0 (1,880-1,900 MHz) cordless phones and cellphones are also not an issue. You only need to watch out for older 900MHz digital cordless phones that use the same radio frequency.+ VOICE QUALITY: Voice quality is decent. The speaker holes on the outside make it appear that the speaker inside is very small, but it actually is an 8ohm speaker with a 2.5" diameter cone on the inside. Sound quality could be improved, but I can clearly understand voice through these units. The volume level can be set to be quite loud. There is almost no audible distortion even at high levels.+ MONITOR MODE: Press and hold the monitor button for a second to enable monitor mode where all the units in your house set to the same channel can listen in on the audio from one room. This is handy for baby monitoring or for PC gaming with 4 of these (see full duplex note below).+ WALL MOUNTING HOLES: Mounting holes for optional wall mounting are a nice addition.+ FLEXIBLE CHANNEL ASSIGNMENTS: Each unit can be set to speak and listen on any of 4 dedicated channels or they can all speak and listen to every unit on a 5th broadcast channel.========THE BAD:========- ANNOYING BEE-BOOP & 1 SECOND DELAY: Each time you want to talk on the intercom you need to press and hold the TALK button for 1 second (while continuing to hold the TALK button while talking). During this one second you need to listen to a loud and annoying bee-boop sound. This is really a bad design choice and one of the main reasons why I would not rate this with 5 stars. All other intercoms I have used let me talk immediately to the system as soon as I touched the TALK button. These other systems support fast real time communication between two people without forced delays. There is no good reason for adding this delay and forcing the user to listen to such a loud beep tone (the tone itself is not sent over the intercom, but it is so loud that you can hear it throughout the house warning you that someone is about to start talking). Also the this beep gets louder as you increase the volume to hear others speaking. There should not be any beep, but if there has to be one then it should be set at a fixed quiet volume level that is not so disturbing.- BLUE LED BACK LIGHTS ARE TOO BRIGHT AND CAN NOT BE DIMMED: The units power off their LEDs automatically when running from batteries, but when using an external 12Vdc power supply, the lights always stay lit. In a bedroom they are way too bright! These LEDs are biased to support seeing them in direct sunlight. This is great for outdoor use, but these units are not waterproof and clearly designed to be used primarily indoors where direct sunlight should not be their primary use case. I had to keep the one in my bedroom upside down on the night stand until I can take it apart and mount *** 8 sheets of paper *** over the LEDs on the PCB inside to dim them enough. It takes a lot of light to still be visible through a stack of paper 8 sheets thick! If you aren't that type who enjoys taking products apart, then you could just run your bedroom units on batteries if you don't want to be bothered by the bright blue lights that can otherwise not be dimmed.- BLUE LED LIGHTS BLEED BETWEEN BUTTONS: The LEDs are so bright that they bleed onto adjacent buttons. For example, when a unit is set to use the broadcast channel all 4 channel lights are lit. This creates so much light that an adjacent "monitor" light also appears lit as does the TALK button. A better internal light guide design could solve this problem.- LACK OF NON-VOLATILE STORAGE: These units need to be paired together to form a wireless network of intercoms that can communicate between each other. I was a little disappointed to learn that after the units are paired together, they don't store the pairing data in any permanent non-volatile storage (such as an EEPROM or Flash). Instead the pairing data is in RAM and the units need to be paired again each time the units loose power (when you move them or have a power outage without batteries installed). Not that big of a deal, but for such high quality units I expected this $0.20 upgrade to have been included.- NO POWER: Batteries are not included (uses 4pcs of AA). The manufacturer claims 1yr battery life, but I do not want to deal with weaker performance as my batteries age. Therefore I decided to use a wired AC/DC power adapter. The manufacturer does not include enough info in the product packaging to help you decide what adapter you need to use. I am an electrical engineer and I would recommend using the "Genuine http://amzn.com/dp/B002RL8IGI/?tag={komponelektr-20}SYS POWER SUPPLY AC-DC 12V 1A AD12V/1A-SW" power adapters work great with these units:http://www.amazon.com/Genuine-http://amzn.com/dp/B002RL8IGI/?tag={komponelektr-20}SYS-POWER-SUPPLY-AC-DC/dp/B002RVT6M8/ref=cm_cr_wr_img- NOT FULL DUPLEX: I searched all over the net looking for good quality full duplex wireless intercoms so that my wife and I can talk to each other at the same time while playing multi-player PC games together. Sadly thee units are only half-duplex (only one person can speak at a time). However I have enough of them so that I can move a second unit into each of our offices, set them to different channels, enable monitor mode and effectively get a hands free full duplex speakerphone connection between rooms when we are gaming. I really wish manufacturers would add the term "full-duplex" or "half-duplex" to their manual spec pages to help us figure out what we are getting before it shows up in our mailbox.- INDUSTRIAL DESIGN: The ID is certainly more modern looking then the previous designs from this manufacturer, but it still looks overly bulky and a little cheap at close inspection. The 4 x AA battery compartment waists quite a bit of space, but even with batteries this design could have been a lot slimmer making it look much more modern.

And the problem is having to wake the kids up in the morning to go to school. They are upstairs and I used to have to trek up and down a couple of times each morning. We put one in each bedroom, 1 in the living room and 1 in the study. Problem solved.

After researching wireless intercoms this is the only one that I found which was portable, clear and very easy to use. With this intercom I can hear my wife call wherever I am and when I am watching a loud show on my PC. My new house has three levels and I needed three boxes.If you need an intercom this is the one that I recommend. I would have bought all three units from Amazon but the main unit were back ordered.
