I bought one last year (i have a bit of a thing with torches - a bit like my missus with shoes!). These torches while not expensive and with a high spec (on paper at least) are a poor quality copy of a very good design by Surefire (I have tried to paste a link to a source of the original products below but if that does not work just google surefire torches).
I bought the CREE 200 version and was initially quite pleased - nice and bright, and felt quite sturdy. It lasted less than a month before it stopped working so I sent it back and was sent a new replacement. That lasted less than 3 months.I took it apart to find that water had got in (although that was not the real problem) and that the connection between switch and LEDs was flimsy and had come apart. I sent this one back and was told I should not have got it went and never got a refund or replacement.

They were designed originally to a military spec to provide a very high output light for military ops (the version you are looking at has a crenellated bezel designed to be used for afflicting injury at close quarters - real nice idea - just what you need underground!).
You can expect to pay between £50.00 and £300+ for a genuine surefire torch.
I bought a bottom of the range version from Surefire in Feb for £49.95 and it's a completely different animal - fantastic bit of kit. The only downside is that it eats a set of battereies in minutes rather than hours which is probably why the CREE version has LEDs now.
I really would not recommend these CREE torches - even a maglite with an LED conversion kit would be a far superior animal (although not as bright).
