If you mean the pulse v2
mod, I really like it, am going to preorder the set that comes with the Requiem
rda.
Thankfully the firmware for it lets you select "leave the wattage alone", doesn't try to force a new power level if you remove and replace the topper.
Otherwise it's definitely the most refined implementation in the pulse series, rounded edges and rock solid door fit.
The bottom fill method works decently, though i often still use a 510 refill.
I also like that it has a coated pcb, have chatted with Tony B about it.
I finally killed my original Pulse X, an extended dip in a kayak gear well [emoji3] It previously recovered fine after a quick dunk in a spa, but after a week it's not recovered from the kayak. I may strip it down, see if there's some obvious location with a bit of water still in it, but certainly can't complain about how solid that
mod had been.
