Review on Disc Lock Alarm Motorcycle Alarm Padlock With 110Db Alarm Sound Security Wheel Disk Lock For Motorcycles Bikes Scooters By D1M (Yellow) Motorcycle & Powersports by Steve Collins

When I opened the unit, I found that there were no instructions, written or otherwise. I contacted the company and customer service was very helpful as I had a few questions about the package. I received two different sets of screws with different head sizes and lengths. It turns out that they are designed to install the block holder on the steering wheel of different diameters. The longest still didn't fit my bike. Another puzzling thing was a piece of rubber with holes in the ends. I found this out after customer service sent me photos to attach the device to the steering wheel mount when not in use. Apparently if you locked it in the holder with the key the alarm would be on and beeping constantly while you were riding the bike. So if you turn off the alarm by unlocking the device, it has nothing to hold it in the cradle. Thus, the rubber band is pulled over the device and keeps it in place while driving. Then when you arrive at your destination you can stretch the elastic, remove the alarm from the mount, place the alarm on the hub and fasten it. It's a good job, but without instructions or pictures it's confusing. The support rep promised me that he would ask the relevant people in the company to attach photos that would explain everything in future broadcasts. I hope they hold on as the alarm clock is a good product. It comes with two sets of button batteries and is loud enough that I can hear it in my back bedroom with the windows closed and my bike parked outside. The only reason they didn't get 5 stars is the lack of instructions,
