Review on 🔊 Vintage Style Bluetooth Speakers with Dual 10W Power, 10-Hour Playtime, FM Radio, Built-in Mic for Handsfree Calls, AUX Line, USB Flash Drive, Micro SD Card Support, HD Stereo Sound and Bass by Oscar Colangelo

Really nice retro speaker, just like the pictures and has all the features described. Good sound, pretty loud I have to say. Good bass system. A full charge takes about 3 hours 30 minutes - 4 hours. There is an LED that flashes green in FM mode and blue in both Bluetooth and AUX-in modes. For USB users, the speaker can play the song that was playing when the speaker was last turned off. All three buttons work perfectly. The female voice announcing the mode the device is going into can be graduated by turning down the volume control (for those who don't want to hear the speaker's voice).
