Review on YSUCAU Powered Security Flashing Warning by Bethany Neal

The product looks great but the battery compartment is too small and breaks very easily when you try to insert batteries. I have two such devices, I installed the first device only when I received the second. If you buy these units you will have to sand down most of the battery case to fit them. I managed to file one device, but the second device's battery compartment broke very easily. I give one star for the looks of the device. The seller must allow the return of this item to avoid getting a bad reputation.
