Review: Absolutely incredible product! It's small enough to fit in your pocket. Transmits audio and a microphone to the radio. I use mine to run my mobile drive-in theatre, and it works flawlessly. I love this product so much, that the urge to buy another one, even though the original product is in perfect working order, (just in case) is strong. I do not understand how anyone could possibly be disappointed in this product. From the quality, to the price, what else do you need in a perfect product?
Review: There are a lot of things to like about this device. - It is small compared to almost any other FM transmitter in its class And has a rechargeable 2000mAH battery that will power it for around 6 hours or more - The antenna screws into a reverse type SMA connector that may require an adapter to connect to regular SMA connectors - Using the SD card to play songs from can eliminate any hum problems as does the digital link over USB and you can set Random mode in SD play - The unit has a builtin mic you have to yell into to be heard and a separate mic input and comes with the external mic as well - It has a setting for Preemphasis of 75uS or 50uS. 75uS is used in the US but after trying both settings I can't hear any difference for whatever that is worth. - The overall sound quality is excellent, and hum free (actually best to keep antenna away from your other electronic equipment - like on the roof). - Lastly I measured the power output on this and found it was outputting 0mW on setting 0 and 1, then 230mW on setting 2, and 210mW on setting 3. I got so curious I bought a second one and measured it: - The second one outputs 0mW on 0, 191mW on 1, 330mW on 2 and 365mW on 3. Kind of nonsensically spaced power levels. So if you are trying to follow FCC rules - measure the power out of this thing and make sure it is under 100mW before connecting an outside antenna. - If you use the little antenna that comes with it, it is tuned for 91MHz +- 1MHz, and is a terrible antenna for the rest of the FM band - Controlling the device is dirt simple using the intuitive keypad Cons: - Did I mention it comes with a terrible antenna? - You won't know how much power it puts out unless you measure it.

*by S***N on 17 July 2021*

I bought 2 because I thought it was a good overall value. Good signal strength, but a little dirty. It elevates the noise level in the FM band, more than it should, making reception of weak stations more difficult. Noise level is about -40 db or -50 db on the station close on the dial I decide to use. Ideally it should be around -60. Broadcast transmitters are usually closer to 70 db. The noise sounds alot like HD hash. I sometimes use it in my car too. For some reason one of the inputs on one of the units stopped working the other day. Not sure what going on. Microphone input is still working though.
