Der Kicklochstopfen meiner Bong war kaputt also habe ich diesen bestellt. Sitzt, wackelt nicht und zieht keine Luft. Perfekt. Außerdem ist er im Vergleich zum alten angenehm leicht und sieht an der Pfeife wesentlich geiler aus. Was will man mehr.Schmodder lässt sich übrigens auch problemlos von dem Ding abwaschen.

Isn’t actually air tight so it leaks if used for cleaning. Garbage product. How do you mess up a 14mm joint?

This product is light, fits 24/40 ground glass connection, is thin glass but not meant to be abused. Pricey but good quality wise.

Compré 5 tapones exactamente iguales en otro escaparate (en USA) y salió a 3,11 euros por tapón (transporte a parte, claro...) Era de esperar pero son vacíos por dentro, y algunos ni siquiera entran del todo en el adaptador, lo sé porque las pinzas no entran bien debido a que el cono es irregular. Puede darse el caso que el tapón tenga curvatura debido al enfriamiento del vidrio durante la fabricación.He visto diferentes precios de tapones durante meses, y hay que son macizos pero valen como 30 o 40 euros la unidad. En esos temas es mejor buscar hasta encontrar algunos que sean buenos y que no tengan un precio desorbitado.Recomiendo comprar en USA todo lo relacionado con equipos de destilación/ adaptadores y demás, Stonylab (la que he comprado este tapón) tiene escaparate, al igual que laboyglass. Son dos empresas que recomiendo.

Recieved my glass stopper quickly. Well packaged, material feels and looks great. Have not used yet for my distillation, but once I have I would update review.So far I have no complaints.

Perfect fit for sealing "glassware" joints during cleaning.
