I’ve only had mine for a couple of days now, but I’m finding it to be very enjoyable to use. Love the switch – I borrowed a Natural from a friend, and didn’t care for the stiffness and throw of the Natural’s switch. The iSeason switch is much more comfortable to use. Build quality is very nice and solid. And, I have to say, I (sort of, kind of) even like the beauty rings (got them in red).
I haven’t modified mine as of yet to deal with the spring issue, but out of the box it’s performing fine with a 1.7 ohm carto tank. I’ll deal with the spring issue before my RSST arrives.
A question in terms of the spring: there’s some silver-coated beryllium copper springs with the measurements of .228" OD x .036" Wire Size x 0.860" Free Length on Amazon for only $7 for a pack of 10. I know the iSeason spring has an OD of 0.300. I was thinking of getting a pack and seeing if I can stretch out the spring diameter to fit. Think it would work?

There are some 0.300 diameter springs, but they are $23+ for a pack of 10.
