It does what it claims to do. The 3-second lock on the flashlight is effective at keeping the light off in your pocket, yet very easy to use in practice. I'm very glad that you can easily turn the light on and off without cycling through various intensities and the ever-present (but mostly useless) strobe. And the pocket/ hat brim clip works well without getting in the way or getting caught on car seatbelts etc. The magnet could be a bit stronger (it only seems to work in one horizontal orientation, not completely handy with the side floodlight), but was handy for working under the car at night. I haven't used the blade or screwdrivers tools much yet, but they seem effective and useful for small work. So far, I like it!
