ENG: shipping in 4 weeks from CHN to SVK, well packed, works good, transmission distance as discribed, by usage of lower transmission 100mW is the distance about 100m, it´s good enough using in family-house and around to 100m distance. The metal housing of item is still cold. By higher transmission 500mW it´s getting warmer. It´s working quite has no cooler/fan as higher types. You need to set a free frequency with half a volume on your input audio device (as described), with higher volume U can hear an interference of audio signal. Some audio-experts would hear depending on your receiver and tuner a little noise if U switch off the input audio, but it depends also from tuner receiver. For that money I can just recommend.
Good built quality, decent sound quality for the price. The in-box 3.5mm audio cable is not ideal, collected some noice on the first try. Given the usage of this product, it should come with noise reduction audio cable instead a regular one. But you can easily find a replacement at Walmart, or go with cheaper/quicker solution wrap it with foil. After replaced the audio cable, sound came out from my car radio was nice. Over all nice buy for the price. cannot go wrong with this budget transmitter for casual broadcasting.
