Just replaced a Black Diamond one which had a faulty switch with an Alpkit Gamma.
Baulked at the £50 replacement cost of the BD torch, though I was concerned that the Alpkit one might be a case of YGWYPF.
It was delivered today and first impressions are very favourable. Much smaller and lighter than I'd imagined (125g inc. batteries on the kitchen scales), build quality looks pretty good, versatile range of modes, excellent "brake light" function, rubber seal on battery compartment.
Still to perform a light test, but looks like cracking value for £12.50
(This from a self-confessed gear snob!)
