I am not happy at all with this product i bought 3 because i read the previous reviews n i went for it but unfortunately one of it is just bleeping every 40 seconds i had to remove it others are still working but i ope the rest will not malfunction like the third one and as it is malfunctioning ive cleaned it as suggested in the manual but still bleeping every 40 seconds what should i do with it now as described

Decent alarm for the price looks quite stylish and its quite small not used yet but looks well made and durable
