Not recommended. Almost not used. In the cold it just blinks and doesn't work. Now I suspect it was blinking so hard it was draining the battery. There are expensive lithium cells in there (4 of them in two different sizes?!) so buying new is probably cheaper than buying batteries. -1 star for not working in the cold, -1 star for the flashing that drained the battery, and -2 stars for not having a rechargeable or even removable battery.
