Which one of these two is better? Any other mods at a similar price with similar features that it would be silly to overlook??
Thanks

I have not had a reason to work with VL CS but they do make it clear, the things they cover for how long and what cost will be outside of those parameters. I think you will eventually find a lot of modders protecting themselves in a similar way.
Unfortunately- due to a change in design meant to accommodate
all of the various atomizers and cartomizers- we were forced
to drop the reverse protection feature several months ago.
As a result- you can no longer reverse the batteries
for 'stealth' mode in any of our units.
