Review: REALLY good sound and range, Worth the price - So far it is great. Tested the range with a handheld radio on the low power setting and could still hear the music a couple houses down. From inside a car, I was amazed at how good it sounded. The audio quality was as good as you might get listening to the song directly off of Spotify. There is a slight hum when no audio is playing but it is very quiet, and I can hardly hear it. The buttons on the front panel do seem to be a bit wiggly but isn't an issue. The size is very close (albeit a few inches bigger) to the size of a Raspberry Pi (which I am using to control my light show). If you don't set the volume knob correctly you will get lots of distortion, but it was not too difficult to set the volume so that there is no distortion. Going into this purchase I was nervous with some of the reviews but, now that I have tried it, I can say this is a very good transmitter and I think it will work perfectly for my light shows. :)
Review: Holiday 'show' - Using this for transmitting audio to go along with a projection mapped house display. Easy to set-up, and using the 'low' transmit power it is clear for about 50 yards around my house, which is all I need.

### ⭐⭐⭐⭐⭐ Holiday 'show'
*by P***N on January 14, 2026*

### ⭐⭐⭐⭐⭐ Works Better than my old Whole-House
*by K***E on September 14, 2022*

I took a chance on this unit, since the power switch on my Whole-House FM transmitter became unreliable. I'm glad I bought this one. Note that this is $79, 1/2 the price of the Whole House, yet puts out about 2x the power. I use it on "Low" power, which is 0.5mW. "High" is too powerful and distorts the audio on my nearest receivers. Note that there are other versions of this unit that are about 2x the price (about $150). This $75 unit appears to be exactly the same as the others. There is also a newer version with an extendable whip antenna. I wanted this one for $4 more due to the helical, short antenna which seems of higher quality. The display on this one is brighter than the new one, too. The tiny power button on this one seems flimsy, so I'm leaving the unit on 24/7, even though I only listen to the radio about 8 hours a day.
