As I recall, most of the glass breaking complaints on the kabiku thread were before the silicon o rings were commissioned by Zen (HOH).
The original buna and especially the white and colored buna at Square up are much tighter....and work well on some poly or glass from other suppliers when the silicon seems too loose.
Glass breaks. Personally I've lost just as many mods as tank glass in falls....but not one ProVi.
