I've had plenty of mileage out of this headlight. It's perfect for so many things you wouldn't even consider. Working under the car, fixing your PC, moving boxes around up in the loft, walking around the house at night pretending to be a cat burglar. The uses are endless.
It has enough modes of operation that you can select the level of lighting you want. Even with only one LED of 5 selected, this thing is *bright*. I mean painfully bright if you look directly into it from up close. If you ever wanted to interrogate someone, you wouldn't go far wrong wearing one of these things.
As well as the variable levels of brightness (useful if you're lighting things close or far away) there's a flashing mode which you can use when riding a bike or attempting to land aircraft onto your head.
It's pretty robust, and the angle can be adjusted in small 'click' increments, and when you set it, it stays put pretty well.
The headband is large enough for all but the most massive heads (more on which later), and is adjustable down to child size. The torch has a piece of foam padding on the inside at the front, which is designed to stop you getting a 'Ring' logo branded onto your forehead.
It doesn't have any form of moisture seal, so if you get it very wet - like when cycling in the rain or cave diving - don't expect it to function reliably. However, the electronics appear pretty basic, so I'm sure a spell in a nice, warm airing cupboard would work wonders. It's worth noting that nowhere does it state that it is waterproof.
So only 4 stars? Well - the foam padding could do with being a tad more erm, padded. After a while, it can start to press into your head, and if your head is as big as mine, you won't be able to loosen the straps enough to exert only a very light pressure. If it were softer, it wouldn't be a problem, and I'm sure for the vast majority of people with normal sized heads it would be fine. The other minor criticisn is that when dropped or knocked (e.g. if you whack it on something while you're wearing it, like a catalytic converter or a roof beam) it has a habit of shedding the front cover and the 3 AAA batteries held beneath. The light goes out, and the batteries roll away into the darkness, quietly taunting you.
So very good, but not quite perfect.
Recommended for normal-sized headed people who don't go pot-holing much and aren't as clumsy as me.
