Got my Ultra max with the RES yesterday,charged a 17670 this morning.I was a bit dubious about the RES abilitly to wick BWB juice,and the amount it would hold,however,It works pretty dam good so far.
And the customer service,shipping are top notch too.
Excellent, I love it that these are getting out! I've been up to my ears in parts and wondering where each one will end up..
