This operated as described. It puts out a clear strong fm stereo sound. I’m using it for my xm radio to connect to my Cardo helmet communication system. Works great.

This is my second whole house transmitter. the first one died of old age. We bought another to replace it. The second one did not transmit at all. plugged it in with all the wires in the proper place and set the channel and it did not work at all. No transmission what so ever. I returned and bought another brand. What a disappointment.

Love this! Got it today to try to broadcast sermons to our church parking lot. It works! I added batteries (3 AA), used the small rigid antenna, played an mp3 from my phone with the supplied cord, set it at the front door, then drive the parking lot listening on my radio. Flawless reception. That’s all I could ask for. I admit it was a 5 minute test, but wow! Next up is trying on AC power, other cords and inputs, etc. for now, I give it 5/5 stars.

Besides taking 2 weeks longer to be delivered than advertised the transmitter puts out a relatively weak signal so the sound is not great.

Signal range was about 50-60’ in a wide open clear area. Anything beyond that signal dropped very quickly. Great product If you only need 50’ range.

Having never used an FM transmitter before, I had no idea what it would be like to set up.No trouble at all, as it turned out. Unpack, plug into electrical outlet, plug a sound source into the "line in" jack, turn on, choose a frequency and you are all set.Only difficulty might be finding a frequency that is not used in your area, but the signal from the Whole House transmitter is so strong it seems to overpower any radio station that might be on that frequency.Over all, very easy to set up and use.

Works great! Able to get all radios in my home with it, even in the basement. Have it connected to my Sirius boom box in the microphone outlet, the only spot available on that unit. Used the mon instead of the stereo and it works great. To increase the volume, I just increase the volume on my boom box and then increase the volume on each radio. That way you can get great volume for listening.

This was an easy and cheap way to send music all through my house. Now I can walk through the house with the same music (usually a baseball game) on all the various stereos, alarm clocks, etc. in the house with no lag between them. Compared to setting up $100 per unit AirPlay or other receivers, this has been great. I even got out my old walkman for listening in the back yard and it's fine. The quality is not "hiss free CD quality" but it sure beats running wires to each room, or a herd of $40 apps to send sound from your computer to your phones and old iPods. We already know how to do that - it's called radio.I do wish it were legal to use the longer antenna. Oh well. It took about 15 minutes to adjust the sound output from my computer to the right level. The sound is quite passable. Some radio receivers are really awful. My alarm clock (iHome) is actually excellent, but my cheap-o iPod/FM receiver is terrible, and it has ultra-fine-tuning FM ability, which might be the problem. My ancient Sony AM/FM alarm clock with analog tuning is great. My Sony digital walkman is decent. It seems that a wider receive range from an analog tuner picks up better, but the digitals are passable even then. You do still get noise from other devices, typical of FM. In my bathroom I have to put the radio up a little higher to get around a noise spot. This isn't the fault of the transmitter, and is quite easy to deal with.Pricing a higher fidelity (near CD quality, wired-in, whatever) solution tends to run very expensive very quickly - either needing to buy multiple small units and speakers for various rooms, or a new stereo with wires run to multiple separate rooms, with speakers. Sending audio directly from a computer to an iOS/Android device runs around 4-40 dollars per device, and still, no power, no speakers. They may offer more control, higher quality sound, and so on, but I was not after a whole-house single audio system. I just wanted to be able to hear the same game in the garage as in the kitchen and office. With one purchase I was able to do that, and no apps, no wiring, no drywall repairs, and far less maintenance.

I purchased this to get 2 stereos in different rooms playing the same thing, from a Grace Digital Wireless Internet Radio. The 2 stereos are about 50 feet apart and the signal has to pass through 2 old plaster/wire lath interior walls.Setup issues: The signal was always pretty strong, but initial problems included "reverb" in the sound or "tinny" sound and distorted bass. At first I confused this with a weak signal, as it sounded like an FM radio station 100 miles away. I was ready to send it back, however, various experiments proved this was not a function of the signal strength, but 1) a poor connection in the (included) 3.5mm "line in" jack (which lots of jiggling eventually worked out), and 2) plenty of attention to lowering the line-in volume. After that it sounded great. The sound is not perfect, like the stereo where the source is plugged in directly with RCA cables, but the stereo sound is still excellent and quite acceptable. I also got more consistent results when using the Aux Out from my stereo to feed the unit, instead of the Internet Radio directly, due to more consistent volume levels I guess.Good Range: I can get in my car and surprisingly it doesn't really start fading until I am a several doors away on my residential street. And this is using the U.S. "legal" 6.5" swivel antenna that comes with it, located at the back of my home.Low volume: You are going to have to turn your remote stereo up to double the usual volume level, because if you try to turn up the volume level on the source device or try to turn up the "line in" volume on the unit, you are going to have terrible distortion. I adjusted the "line in" volume to about 50%. This made it sound good, but again the volume is low. You won't hear much static, but because your remote stereo will have to be turned up very loud, you might hear a bit of background static.Hum on A/C: This was the most annoying problem of all. I started with batteries, but the 3 AA cells were running down after several hours of use and the quality and range began to deteriorate significantly. I decided I had better plug it into the wall (using the included USB power cable and 120V A/C to USB adapter, but I had avoided that because this caused the unit to broadcast a very noticeable 60 cycle hum. I tried to solve this by soldering a 1000uF capacitor across the 5-volts on the USB cable, but to no avail. Eventually I resolved this by using the (included) car cigarette lighter to USB adapter, with a high quality power supply I had lying around, which converts 120V A/C to 4-amps of highly filtered D/C in a Cigarette Lighter receptacle. No more hum using the cigarette lighter adapter, but you are probably going to spend maybe $50 getting a high quality A/C to 12-volt power supply. However, when compared to the cost of a Sonos wireless system to do what I am trying to do, this unit is still a real value.Summary: The 2 things I wish the manufacturer would address are 1) the awful hum from the A/C power adapter they provide, and 2) broadcast at a higher volume, since the input volume must be low to avoid distortion on the output. Still, since I have resolved the hum on my own, and since I can live with keeping the remote stereo turned up louder than usual, this unit is a Keeper. With its good range and excellent sound quality, I can recommend it.
