Mine came today via USPS. There was an issue with the shipping email and I couldn't see tracking info. I just finished charging one and will test it outside tonight. The instructions are wrong. It says to initiate turbo mode you hit the tail switch twice. You actually turn it on and hit the side button twice. It seems very bright. With the loud color you'd be hard pressed to lose it outside. For $15 and free shipping it's a solid deal. They are showing $19.99 now and the black ones are back in stock.
