The case is fully transparent so there is no Fresnel lens effect at all, resulting in it not being as bright as I expected would have. While there are seven lightning patterns to choose from, they're all pretty mundane. Being able to iterate through them all in a repeating pattern would be great too. The mounting magnets seem to be stronger than the magnets on the last flashlight I had that stayed on in 3 digits, so I don't think there's any risk of the unit blowing off. If the light was brighter I would give this product 5 stars.
