Kudo!!

I'm about 2 years and 5 months late to the party!
I'm thinking of buying one of these (The FG 500 Hydroponics Dripper)
I did an AFN search and my old buddy Kudo came up! ^_^ WooP!!
Is this similar to what you were using?
Can i pick your brains?? ^_^
Is the rez easy to change and get to for PH and EC testing? (can't find any useful info online)
How long would a rez last on an average auto in flower?
WOuld you recommend it to me as a (potential) first time hydroer
