Selbige phenomena as with the previous speaker. The cable attachment is attached with screws to small, it almost falls itself off, if one uses the light stick. Waterproof is then nothing at all, and I doubt if the construction be truly waterproof, or should only appear waterproof. The distance between the contacts of the lamp holder is too large. There is no contact, which is why the thing then is off. Therefore: Terrible! Starting in the dustbin. The thing does not go. But at 8 Euro me every complaint is too expensive. Just get rid of it. Who buys cheap, buys twice.
