Expensive at the time I bought them but I prefer these to others at the same price point. Easy to use and fit/remove quickly/regularly, good batteries last well, you would really struggle to break these things, bright enough but along a norrow beam, need to make sure they're pointed at the best angle - like any other light.
Have owned this for about 6 months.It was good while it worked properly. Performance became erratic 2 weeks ago (some functions did not work,or only sporadically and the steady 3 L.E.D. would stay lit for 10-15 secs then go out). Now reduced to one brief flash, from one l.e.d. only, when 'on' button is pressed, then.........nothing. 2 sets of new batteries tried, plus cleaning contacts has made no difference. This will be returned for full refund just as soon as I remember where I bought the ******* thing and can find the paperwork!
