I bought boat airdopes 161 pro and after two months one side of the airdopes was not working properly and I claimed the warranty the upgraded piece received today but iam totally dissatisfied because the product is very bad the normal mode and beast mode changing automatically and right side is not working properly in my perspective view the product is a big $#*! I request others don't buy this fake product from boat site service is very much disappointing there no worth of giving one
