Review on 🚨 Baomain Industrial Flashing Warning Buzzer by Robert Howell

Do not buy this item if you do not speak Chinese. The packaging has cryptic connection instructions, but they are so confusing that they become unusable. I've tried connecting this device multiple times but couldn't get it to work. Sent it back to Revain for a full refund. I wouldn't buy it again and advise others to stay away from similar products that don't have clear instructions on how to use them. Revain, you should not store this product.
