My whole family has now already as a small lamp for the keychain. We are all very happy! The light is more blue, whereby the lamp actually has a very bright light. In addition, it is very robust and indestructible;) The battery that is included now holds just over 2 years, and the lamp is used frequently despite still quite light Practical and small Alltagsbegeiter.. Whether you need to unlock the car in the dark or at night looking for the keyhole. But also wonderful instead of a large flashlight to use.
