Just remember that, like with anything else, there is a learning curve to dripping. The key is to not get all mad and frustrated when you get dry burns, flooding, or even pop an atty or two. We've all been there, and learned what we can/can't do with an atty from it.
Also every kind of atty functions/tastes a little different. So just because you don't like the first one you try doesn't mean you won't like dripping.
For example lots of folks point & snicker when I say that I modify LR 510-T atties for my drippers, but I like them best and that's all that matters. So don't be afraid to try a few different atties, and decide for yourself which you like best.
As for the life of an atty, when I first started dripping a week to 10 days was average. Now, 6 months to a year is average.
