So paper strips have been serving me OK but I seem to see many experienced brewers blowing them off and citing inaccuracy due to all kinds of reasons so what's the board think? Amazon has ones running in the low to mid teens to a couple hundred bucks that are high tolerance (+/- .1) which for beer I think is just fine to get in that sweet spot of around 5 and these measure down to 2 decimal points which is much better than the paper strips I have been using which are one decimal but put your scale in a .2 step ( 5.0, 5.2, 5.4 etc.). The problem is that the Amazon reviews are all over the place including an engineer's comment stating that you may as well use your nose which I thought was pretty funny! Any recommendations from any of you??
