Review on 🔊 HYDRA Tech Bottle - 5W Bluetooth Speaker, 4000 mAh Power Bank Charger for Smartphone, Speakerphone, Microphone, RGB LED Nightlight (Emergency), Black by Tyler Cooley

It does what it says on the tin, the speaker is quite loud, FM radio is a bit more difficult to use, can't have too many settings as expected , but that's it works great, just like advertising. There are negative points that you will see after you get it, some of them are that it is a bit clunky, there are no instructions for it for some reason, so you have to search the web for all the features.
