recently bought a bunch of conti tubes off wiggle. 4 punctures in 3 wks. in good weather too...all three punctures looks like a split in the 'seam' of the tube. im buying more patches and switching back to vittoria tubes
continental tubes are a bit shite. i've been through three since i've been here in berlin. same quality control issues, often splits at the seams. i'm not a fan.
I've used conti, schwalbe, specialised and vittoria tubes previously and I only got punctures if I used shit tyres eg Conti Ultra.
ahahahaha see? Conti = devil spawn. :)
