Use the head with a Canon HF G30 (about 1kg), which unfortunately is a little too light for the preset counterbalance. An adjustable compensation for the price is just not there. But can be corrected with a little gentle setting of the brake. For slightly heavier cameras or DSLRs he will probably be better balanced (preset to 2.4kg).
Otherwise a very good video head with good quality and very nice pan / tilt response. Use it in conjunction with the Manfrotto 055XPROB, which I think is a pretty ideal combination.
