Good device, sounds great, ZERO install help in box, search online and HARD to find correct instructions, initial bluetooth sync sequence NOT intuitive, large circumference - glad I'm not any taller (5' 11"), mounted in 2021 Polaris Ranger XL 1000 Trial Boss from roof in front of passengers. Took 3 hours to install properly day one, could not figure out how to sync, had to wait until next day when I had time to search internet to find correct sequence to sync to my iPhone.
When using the app the volume shoot to max everytime you change screens. The sound is just ok no good quality., and when the lights are on there is a hum coming from the speakers
