I just got mine. Well condition of the strobe has lot to be desired. It seems used yet not abused. Manufacturing quality of the cap for the new batteries is excellent. It even has a nice o-ring to keep it waterproof. I ordered a set of filters from him as well. Now here's a question for members who allready used one. I put fresh set of batteries in and turned it on. First couple of flashes were really strong and than they got dimmed and kept at the same level. Now they just vary in power. Is this normal? How strong the power output and how frequent it should be? How longs should the batteries last?
