This is an excellent little transmitter that does everything it claims to. The range and fidelity are very good, the Bluetooth interface is easy to use, and there are some nice features such as readouts for forward and reflected power, as well as internal temperature. There is also a warning for over-temperature or bad SWR. My only complaints are that there is no setting for 0-6 watt power – the unit produces 0-15 watts, period; and the fan turns on and off constantly, may be a problem when you’re using a mic (cheap condensor mic with 1/8” plug works fine). A 4-page pamphlet in decent English explaining setup and use comes in the package.The PC Control software doesn’t do anything more than the controls on the transmitter face can do, except for allowing a playlist to play automatically; however there is no info on how to do that. Easier to just do the playlist on a tablet or phone and connect with Bluetooth. (Make Bluetooth connection from device to Niorfnio, and then audio from device will be broadcast by transmitter.)If you want to use the Windows PC control software, you need to request the web address from LIDI-US (use the link on the Amazon product page under "Sold by" and use the "Ask a question" button to request the web address to download PC Control Program – email will not go through, but you will still get a response, download is from a Google Drive website). At that website, download both the “NIO PC Control V2.1.rar” and “6W 15W Drivers CP210x_Windows_Drivers.zip” files. Install the x64 version of the drivers. To use PC Control program: connect a USB cable from the transmitter to the PC, start NIO PC Control program, login as Admin (Admin password is count to 6), then click "Connect" button -- you'll see data from transmitter when it connects, and transmitter screen will flash "PC". But for most users all this may be more trouble than it’s worth.

Easy to use. They even give you a tape measure to adjust the antenna length to match the frequency you're using. Control is easy and sound quality is great. Zero 60 cycle hum. There is a forward and reflected power meter built in and the power is adjustable. Typical Chinese translation issues in the instructions, but they are good enough to get the unit setup as needed. Very satisfied so far.

This transmitter is a poorly designed piece of Chinese junk. Even at it's lowest power setting, this transmitter's output contains a lot of harmonics and spurious signals. If you live near others you will seriously impact their FM listening and may get a visit from the FCC. The listing says this is a FCC certified transmitter, I assure you it isn't. It would never pass their testing. My advice, don't buy this transmitter!

Works as advertised except the Bluetooth feature is absolutely horrible and has very little volume to the extent that it's mostly unusable. I use mine with an Amazon echo dot connected to the line input, and it broadcasts the FM signal to a boombox that I take in my boat. I get a reliable audio quality signal all the way across the lake I'm on, which is about a mile away from the transmitter located in my cabin. However, please do not try to use at max output power with the whip antenna connected directly to the transmitter, or you will blow up your device quickly. On higher output powers you must locate the antenna away from the device via the coax cable supplied with the unit, and preferably attach the magnetic mount portion of the antenna system to a metal object, so you create a 'ground plane'.

This transmitter seems to be good quality and works just as advertised. Controls and included antenna all good. The frequency is stored and returns next time turned on. Very stable frequency. Included instructions are fairly clear, but I had to use my thinking to follow the menus. I am very well pleased.
