    Do you keep your cooling-liquid-temperature low enough? (~19-20 degrees Celcius .. ~22degrees max)
    I spoiled my first tube within a year, probably caused by insufficient cooling (in summer up to 35 degrees...)

    i think i did... at least, my cw5000 chiller said it was at 20 degrees celsius... the room have AC, to avoid being hot in summer or too cold in winter times... starting chiller at least 45 minutes before laser, to alow water to be cold enough (not too cold, to avoid condesantion)...
    i did respect the amps, too...
    so, no, i don't wanna belive it was my fault...

    but becouse of the efr policy to send at least 4 tubes, i will go for reci again becouse (again becouse) i don't have anyone to split order and can't resell the tubes because of warranty reasons (for new electronics law say you have to honor at least a year warranty)

    I bought my EFR ZN series tube off ebay. Very happy with it. "sign-in-china " was the seller, arrived 1 day late but other than that, so far so good. I ordered on a Saturday it was supposed to arrive Wed-Fri but arrived the following Monday. Very well packaged. Popped it in an it worked like a charm.

    how many days traveled? 1 day more or less should not be a problem...
    it came by boat or a fast delivery air service?
