The SuperTrickler looks to be a much more finished device. That it learns is innovative. Freeing up my iPhone was also a plus. I like that it alerts you when it goes over with the bold red light over the cup.
I had to try it and figured if it was as good as it looks, they're going to be hard to get before long.
The V4 is what the AutoTrickler should have been all along. The powder throw mechanism on V1 through V3 represents little by way of novel thinking and innovation when developing an automated solution to powder dispensing. Don't get me wrong they're great devices and vastly better than their contemporaries, but they're little more than an automated powder thrower and trickler integrated with a lab scale.
The degree to which the SuperTrickler is it's own device and a truly novel solution compelled me to order one as soon as I saw one.
