The specification is clear enough. Fully extended, you can add 0.9 kg and certainly not 8.5 kg. You have to imagine that. A wobbly lamp tripod extended to almost 4m and 8.5kg attached to it? Hardly.
According to the information found, yes :)
Description: Quick assembly. Durable. The black aluminium pole tripod with sandbag is an extremely flexible and sturdy pole tripod for your photography.
