This is another one of those inconspicuous gadgets that initially seems like nothing, but actually does serve a real and very useful purpose. There have been numerous occasions over the years when I've needed some form of light in the evening to either find something that I've dropped, or just to find which way round to put a key in a key hole, and this little micro light has perfectly solved those dilemmas.

For around £4 from Amazon, what you get is a very small stylish LED light that attaches to your key ring, which is housed in a water resistant casing that is about the size of a large oval shaped thick coin. A small chain comes off the back of the casing and leads to a key ring, allowing you to attach it to other items (eg car key ring) or to attach other things to it.

Looking at the casing itself, there is a small rubber covered button in the centre of the top cover, which is matched by another button in the centre of the bottom panel. Interesting, whereas most micro lights only have the one switch, this Cyba-Lite version actually has two, where both switches have a positive firm clicking connection when pressed. What you have with this version is that one switch works as the on switch, whilst the other works as the off switch, which is unusual because often you see these sorts of lights with just the one push switch where you have to keep the switch pressed in order to operate the light. Not a problem, but it does mean that one of your hands is then tied up to operate the light. However, in the case of this Cyba-Lite, you can switch the light on and it stays on because of that positive clicking action, meaning that you then have both hands free to do whatever you need to do.

At the front of this device you have the important bit with the LED light, which is what they call an ultra bright LED. To understand what this is about, LEDs are commonly used to provide a bright light source because they only consume a little power. Hence, their small size allows them to be fitted into small lights such as this, and their low power consumption means that they don't need big batteries to be installed in to the device to power them, again ensuring that the overall size of the device can be kept to a minimum.

Key with this is the low power consumption of the LED which the manufacturers claim to be able to give up to 12 hours of continuous light from the small battery pack, which should be more than enough to cater for most peoples needs for many months, if not years. However, when the batteries do finally get exhausted (and I have still yet to reach that stage after a year of use) they are changeable (2 x CR2016 flat batteries suffice), meaning that you can continue to have many more years of use from this device, without the need to just throw it away when exhausted.

In terms of the light produced, in my opinion this is a light that provides a very decent amount of light, especially credible when you consider how small it is with just the one LED. Forget about trying to find the key hole in a door, this light will light entire paths, large portions of your driveway and most of your room. So when you consider size, price and weight, this micro light is a winner al round.

In summary, as I said at the start this is one of those gadgets that initially seems like nothing special, but actually turns out to be something that serves a very real and useful purpose, and for the cheap price and small size, it is something that is totally unobtrusive and there when you need it. Hence, a 5* recommendation
