I like the Tilt ... *BUT*, what I really, REALLY like is a spigoted fermenter ...
I'd almost recommend a spigoted better bottle over the Tilt ... that, unless you are planning to setup an iOS or Android device next to it to act as a repeater ...
The way I'm using mine, it's not that accurate (need to calibrate both for temp and gravity to improve that aspect - each battery change) ...
I don't get curves on my charts that are true, because they have too few data points because it's only picked up when I walk my iPad over to the fermenters to get a reading ...
So, I like it, but I still pull hydro jars to get the ACTUAL gravity, for sure ... and having the spigot is the key to that ...
I used to resent the sample-loss from using the hydro jar, but I like tasting it critically and getting those clues to the brewing/recipe etc as it's progressing at this point ...
The charts are cool, but I really need to setup a device to repeat them constantly or it's not really worth it - because a) they aren't really accurate, and b) it's a waste of $3/mo to brewstat.us ...
