      We ordered a quantity of these 186050 Batteries for production from M&A BD Electronics, which were advertised as Panasonic 18650 Batteries but upon receipt discovered what we actually received were “IRREGULAR AND UNBRANDED”. We further discovered that these batteries are UNUSABLE BECAUSE THEY ARE "IRREGULAR IN SIZE" and slightly longer than any standard 18650 battery, and therefore did not fit inside any of the professional wireless gear. We immediately contacted "M&A BD Electronics" to bring this "obvious mistake" to their attention along with a photo of the batteries side by side, only to receive a shameful NON-RESPONSE which described the batteries, exactly as we described the batteries received to them. Additionally OFFERED ABSOLUTELY NOTHING, NO EXCHANGE, REPLACEMENT OR EVEN A REFUND, Then to add insult to injury, ended their message to us with " WE HOPE WE HAVE ANSWERED YOUR QUESTION HAVE A NICE DAY .. BEST REGARDS... WOW.. These bait-n-switch Shenanigans may be ok for the non-professional, but if you are a professional or organization, do not buy anything from M&A BD Electronics. That is our experience
