Some months ago Suyi of Auberins asked for my feedback on this thing so I had him make a few changes (like up the events to 9). The thing was already designed and being tested - he send me the manual and asked for general feedback.
The big thing I like over the timer I use instead of this one (and the main reason I chose it over any of the Auber timers) is the 4 discrete time set buttons that are used to change the time. It's quick and easy. On his other timers you have a change button to cycle from 0-9 and a shift button to move to the right. So it results in more key presses. In this new one since everything is minutes (no seconds or hours) the two buttons are up/down and you affect the whole time and the time change accelerates if you hold the button down longer. It's a personal preference, but I hate these sorts accelerating buttons. I always overshoot and end up having to click the button 15 times to get to where I really want to be.
Suyi tells me that to go to 4 discrete buttons would require a complete chassis redesign (as you'd expect, the same chassis is used for multiple devices - only the programming changes).
It depends on the brewer but I also kind of like the simplicity of not programming in events in timer to remind me when to do hops. I’d be worried that I’d screw up the programming and miss an event or put in the wrong time so I'd constantly be looking at the paper recipe anyway. During the boil I’m usually cleaning out the MLT, cleaning the fermenters, etc, so I’m usually around and have (knock on wood) yet to miss adding hops in about 100 of batches now – and I do like my hoppy beers! Some of them have had 6-7 kettle additions.
But that's just me - I don't like automated systems where you do pre-programming of some sort. To me that seems two things you have to check then: You have to make sure you did the pre-programming correctly and then during the brew I'd be extra careful wondering "did I program that correctly?" and always checking the time and looking at my recipe to see if I missed anything.
I like having the recipe printed out in front of me that I know when to add stuff. I suppose you could then also program in the times into the timer as a backup to have an alarm go off, but I've yet to miss an addition in dozens and dozens of brews so for me it's just extra work that doesn't result in extra value.
YMMV of course! There are many ways to make beer, everyone likes to brew differently...
UPDATE: Was talking to someone using this new timer last week and
there was one issue about the timer that they did not like and were going to contact Auber about: You can not set the number of events to less than 2.
