Very pleased with this purchase.
Took a little while to figure out the zoom, focus and strobe/SOS controls (no instructions supplied) but this torch does everything the product description says. The metal casing is very sturdy, so you don't have to worry about dropping it or standing on it.
On the widest beam setting it provides good all-round illumination. The narrowest setting penetrates much further but illuminates a much smaller area. The strobe/SOS functions (which you have to hold the button down to active) would be very handy for hikers, climbers etc.
I've had this torch for about a month now and haven't needed to change the batteries it came with. That said, I don't use it as often as others might (mainly for finding my way around a poorly-lit maintenance depot during short winter days).
Overall, would highly recommend this torch.
