Here’s the thing, at the end of the day, the SION is a good RDA that vapes really well and has some top-tier level flavor. The trade-off is it’s a BIG RDA that can only house small coils comfortably. If you own the SION RDA and your top cap is getting uncomfortably hot… 25mm, pull em out a little bit, make a passage through the wick.
GM did a solid job on this and QP Did ( as usual ) a very nice job producing it. With the exception of The Prey, There isn’t much I don’t love from QP Design.
