Byb has made a very nice and bright flashlight pack! It came with a rechargeable battery, a case for the battery, a recharge plug in, a AAA battery back up pack and a solar power light key chain. I honestly think my favorite part of the pack is the solar powered key chain but that’s just because i love key chains. But anyway this light is very bright and has a slider to zoom in and out of light size. I love how you can either use the rechargeable battery or AAA batteries. Making it eco friendly too. All of the different parts work and I am using the key chain on my keys. I would purchase other products from this company and would recommend this to others that are looking for a very nice flashlight for emergencies or camping. I received this product for free in exchange for my complete and honest review.
