Review on 🔦 USCG Approved Lifesaving Systems Corp Sirius Long Range LED Strobe Light - High-quality Signaling Strobe, Exceeds Solas Requirements - Made in the USA by Tony Addis

First the feedback that the batteries do not fit. I suspect they are trying to use rechargeable batteries that are above specs in both diameter and length (bigger battery equals more mAh). I use alkaline Duracell and they fit perfectly. Just check them regularly and replace them annually as instructed. I am a professional diver and I insist on the highest quality of my equipment. You know, it's some kind of security measure? I highly recommend applying silicone grease to the battery door o-ring and making sure it is free of any dirt or debris. at the same time - seriously), compact, great design, made in the USA cons. Could have included velcro for expensive price :) Note: This is NOT a flashlight. This is an awesome alarm flash that could save your life!
