On paper, this boom looks really good. We have therefore offered to a friend for his birthday. On a recent trip, the opportunity arose to use it for the first time to film the coral and fish. Unfortunately, the self-locking system to enlarge and shrink the pole became hard and even blocked. More serious problem, the upper portion on which is attached the camera (GoPro or in our case) was unsoldered of the pole. Consequences: Can not keep the camera stationary, impossible to enlarge the boom. In short, it is now out of use. And videos that we wanted to have fallen into the water. 40 just enjoy it once, it's really disappointing. I've bought him a 12 (story the poisoned chalice goes better), with a monopod expansion-type system or tripod (not yet tested under the same conditions, the holidays are finished). And finally, between purchasing, birthday and this trip, the time to replace or refund the product has expired. We do not recommend without a doubt.
