evening all; picked up 3 of the above and about to test them tonight, but the plastic cap (condom) at top of wicks and atty looks sqew not straight like its not fitting flush where it seals off the mouth tip and looks like they will leak into mouthpiece into mouth if turned horizontal. slight tiny gap where should be sitting flush to seal mouthpiece. was wondering if i tried it first and it did leak, could i ask for a replacement after i had used it, or should i send it back now unused? thanks...
