I have just looked and it's the 2nd highest result after the official Mathmos PDF which amusingly contains the sentence "There is no need to replace batteries or bulbs".
Well i only paid 5 euros for it. Only needed the charger for other mathmos´ gadgets so.. i guess i´m going to risk it and change the battery myself. i´ll keep you posted. Thanks anyway
Clearly there is a market for these things. Some enterprising soul on Bit needs to start making them.
