I've used 2 so far with no issues at all on a 510 Kabuki. I haven't tried one
yet on a P3 Kabuki. I've heard of 2 people that needed O rings sold at HOH for the P3 Kabuki as they were a bit loose on their 510's without the slightly bigger o rings. Apparently, some of her glass came in a bit off size at one point.
I've enjoyed using Bedazzled decorated glass since my carto days. The finish is baked on and is very durable....not like FT colored glass where the color scratches off easily.
@tyleris12 -- I know you had a couple that needed slightly bigger orings. Did you perhaps use IB tanked o rings or HOH or both?
