Good kit, only few conponets. Easy to assebmly, only battery terminals are more dificult and they are not so good. I was expecting joule thief circuit, but it is not! There is YX8115 LED driver. Datasheet says it can operate to 0.9V, joule thief will work with much lower voltage. There are for some reason 4 resistors, but you need only one. 1/3 of case is unused. It could be smaller or it could be for 2 AAA. Swith should be secured with wire. I did not noticed that, so I secured it with epoxy.
