Review on 🚴 BV Super Bright USB Rechargeable Bike Light Set: Headlight with Free Taillight, Three Light Modes, Water Resistant IP44 - Fits All Bicycles with Two Mounting Options by Brandon Carr

I have bought many of these flashlights over the last few years and found that the battery performance varies greatly from device to device. Battery life varies from case to case with battery life exceeding description but most run in the 60-80% range. My first order for 4 devices was delivered as advertised and when I ordered 4 more the following year I was disappointed that only one matched the product description in terms of battery life. I contacted the seller and they sent me a replacement which worked fine. I bought 4 more the following year and none of them worked as advertised. I contacted the company and they sent me a replacement, only 2 performed better. The other 2 were worse. They sent me a refund. I've just ordered 2 more and they're only running at 80% of their advertised battery life. I keep trying because I get a good one every once in a while. I just want the company to have a reliable product.
