Object gives a very good impression, but package is whitout information sheet. Not specified what battery size is required. AA is too small, C is too large. Maybe A? If yes, near impossible to find in Italian shops. Today I can't light it. Tried to ask to support team, but assistance section of website is unreachable today 11-Jan-2014. The light is still off, without battery.
Hard to find, but into specification i see the battery type is 18650. Only found reachargeable type. Just bought online, some other days before to test the product.
