I've had about Five of these over the past few years Joe. I paid between ?5/?10 for most, but the quality of them has varied greatly surprisingly. The original two I got were brilliant and survived more than a year of diving/caving, the switch breaking was the weak point. I think one of those original two is still going. The recent one's I've acquired have been nothing but hassle, the inner and outer parts of the bezel unscrewing was the major fault when changing batteries. But for the money they're an absolute bargain.
