Review on 🚧 Enhance Safety with the Blazer International C8025 Back-Up Alarm by Jon Dunn

I bought 20 of these backup alarms for use with company trucks at a construction site. Of the 20 I bought, only about 3 are still working properly. Most alarm clocks didn't work at all, or only worked a few days before failing. Whilst I have purchased additional alarms in case some of them fail or become damaged, I did not expect that 85% of the backup alarms I have purchased are defective/completely non-functional. I am very disappointed in this product and do not recommend buying these alarm clocks.
