Zweibrüder LED Lenser K3 High Performance Line

Small and lightweight. Good size for key ring.Well built, nice design and very bright.Excellent battery life.Liked so much have also purchased L7.

Battery life seems good. It's very small, the picture here makes it seem bigger than it is, but it's slightly longer than the size of the average thumb. The telescopic function of the lens (it moves up and down to adjust focus) seems to do nothing, however. On my other LED LENSER, the T7, the telescopic function is awesome, you can easily flick between floodlight and spotlight modes. But on this torch it doesn't seem to do anything at all.It comes with a keyring hoop to go with your car keys, etc.The black coating is just paint so it's not the colour of the body itself; after being in my pocket for a few months the paint has started to fleck off exposing a silvery underside.This isn't a problem at all because it's a tool and I expect some wear and tear.Aside from the paint fading, the durability is excellent. I've knocked the thing all over the place and treated it harshly but it's performing as good as day 1. Sudden impacts haven't damaged the optics yet and I admit I've dropped it a few times accidentally.Brightness is great, and range not so amazing, but given the size of this torch it is more than sufficient. Do not count on this item if you get lost in the woods at night when your car breaks down. For that, I'd recommend a larger model. However as something you can throw in your pocket in a pinch, this is good.*UPDATE* I have taken a star off because (I should have mentioned this earlier as this happened only a few weeks after I bought it) the little metal keyring hoop on the end of the torch is really flimsy and it just bent apart.

Wow, this is the ultimate key ring torch. Button press on and off at end of torch, pull push for beam focus, really bright, solid build, small batteries, is still on the first set and I always find myself using it. Much better than my last maglight, LED so no bulbs to replace much more reliable. Think I might be getting the P7 too.

I purchased this item as I wanted a small bedside torch. Having read the previous reviews I was expecting it to be good but it has turned out to be great.The brightness is incredible for something so small and I love the ability to focus the beam into a tight circle of light.I would strongly reccommend this item and have purchased a second for my grand-daughter.

I have bought several of the larger LED Lenser P7 torches in the last couple of years (one for my Mum, one for my wife and one for me!) and I have been consistently impressed with the quality,features and brightness of the torches that LED Lenser produce!These little key-ring torches are no exception. Don't expect something which fries your optic nerve if you inadvertently look into it like their bigger models, but for something the size of my little finger this is one hell of a torch! It fits nicely onto my key ring, is lighter than my old Maglite solitaire, and kicks out enough light to be useful, unlike the Solitaire which was actually fairly feeble light-wise.I was a little worried when it first arrived that I'd keep knocking it on in my pocket, since the button is on the butt of the torch, but it doesn't seem to be a problem.Be aware that these things are expensive to run; They take the little button batteries (whatever size those are!) which don't come cheap, and it needs 4 of them, so while this is a five-star product for everything else, it loses a star for being expensive to run.

This torch is incredibly bright for its size. I compared it to a key ring Maglite and there was no comparison. You could not see the Maglite due to daylight but you could see a bright, perfect circle from the K3 set to spotlight. The torch is well mad and easy to use and is small enough to fit on my key ring.

Short torch....short lived!

Arrived today so this is provisional comment.Well packaged, spare batteries, instruction leaflet with exploded diagram. Test before you open works - I wish earlier purchases provided this. I expect you could buy spare parts. This is not a throwaway item.Beautifully made, Proper on/off switch, beam adjustment, both of which work properly. "Aurora" on beam as noted in earlier reviews, I can live with this.This is the fourth keyring torch I have ordered from Amazon. One was undelivered, the other two were throwaway products, one throwaway before you use it.One point for Amazon, these items are bought because they are small. So why not take some trouble to provide the size of the item? Many of the descriptions have no sizes. Many have dimensions which are the size of the package. Pull your finger out Mr Bezos.So a great little torch. But a keyring torch? I am not so sure, I can believe the earlier reviewer who said that the lanyard aperture broke, it is tiny and looks very fragile. The remainder of the attachment is otiose. Keeping the torch, but it will be loose in my pocket.
