New to Yerba Mate

I understand a cup and straw are the best way to enjoy it. But i find it hard juggling the traditional way with the lifestyle i live bouncing from space to space with a 4 year old and errands. I've done the cup and canteen of hot water. im looking into the combo yerba mate canteen on amazon, wonder how good is it? also would it be fine to mass brew it in a temp controlled tea kettle with a very fine infusion chamber?

Id like opinions and options from you all.
