We've been using this transmitter for over a year and really love it. It's easy to use, easy to set up, and gives clear channels.

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.

This particular unit has no Bluetooth connectivity. Signal is provided by a 3.5mm cord. The audio quality within a vehicle from this device is SPECTACULAR! i picked up my xmas crystal clear over 1/2 mile away from the base unit! The quality of the device is wonderful and metal. The units size is small but this little sucker is super powerful. It has stereo connectivity, and has very clean audio as a final result. Impressive!!

We were expecting something better, bad product does not work as it should, it is defective, waste of time, I do not recommend it

I purchased the transmitter a month ago for home use. I use it to stream on multiple FM radios placed in various rooms in my house. Sound quality was good but what drove me and the family nuts was a background hum. You would hear it very clearly and strongly between songs. The hum would also affect the overall clarity. I tried various levels, Bluetooth devices, direct 3.5 mm connection, ETC with no avail. I did some search and used some try and error RF suppression tricks until I wrapped a foil around the base of the antenna bolted to the box and another foil around the power supply. That took place of at least 90% of the hum. Now the sound is much clearer, crisper and much less annoying as the hum is mostly gone. Wished they had a ferret core or something provided in the box or at least an explanation of that anomaly and it possible fixes in the leaflet. Overall, I recommend this product as a cost effective solution for those who would like to stream in a larger home with multiple devices. (Also a good idea to search for the least used/busy frequencies in your zip code, this helps with avoiding clashing interferences).

The transmitter runs well, easily received anywhere in my house using low power. Sound is broadcast quality on any receiver. Easy to set up and use. The major problem is the loud hum coming from inside the units case. The hum will lessen if I press a finger to the top or sides, but once I remove it, the hum returns.Amended on Jan 7, 2023: Retekess sent me a replacement transmitter which I received today. It works perfectly, with no hum at all. Very quick customer service, and a promp solution to the problem. I'd order this again if I need to.

Worked great until a brief reverse polarity was applied for power, when we tried to switch power supplies at an outdoor event. Our club's unit is dead as a doornail now. Kind of amazing that there was no reverse-polarity protection. We'll look for a more robust unit now.UPDATE: The seller very kindly refunded us on this.

this transmitter is very well made and very solid. it has a metal body and quality antenna. it is easy to use and transmits a strong FM signal all over my home and yard. the sound is full and strong. it is very easy to use. it does get hot after using more than 2 hours but it worked well ! long live radio ! i also loved the audio cable it came with !
