Purchased an AS250 a few weeks ago to evaluate the product and was very impressed and then purchased a second unit. The AS250 represents very good value for me with good light output, well controlled across the range from minimum to maximum. The output in any given setting is also consistent. There are quite a few basic accessories that are reasonably priced.
Only two small comments in that I would have preferred a 0.25 inch sync socket rather than the 3.5mm that is fitted and for the LED modelling lamp to be proportionally variable with the main flash rather than the off/half/full that is available. Minor points and the first is solved by an adaptor and I will get used to the second over time. In a two head set up they also work well with the Genesis remote trigger.
