Wow, bummer Sandy. Maybe I just got lucky with my 601? I noticed the tendency to leak into the bowl with the first one I had, so I soon developed the habit of "hanging up the pipe to drip dry" overnight. I've had no leakage problems with the bowls I bought to replace the one I dropped and cracked. I have been alternating them to even out the wear, so even though I'm approaching The Dreaded One Month Mark, they'll probably last thru December. I see no reason why they won't go longer still. I think the extra attention I have to give the 601 is a fair exchange for the drastically reduced price. It's really almost no effort at all considering all the crap I had to go through to keep my super-mini going much less producing a consistently decent vape.
However, given your experiences I'm going to start setting a few bucks aside towards the purchase of a genuine Ruyan. If the 601 is heaven, then the Ruyan should be Heaven with Bacon & Beer!![]()

I admit, I'm the lazy one amongst the vaporers. So I just leave my ruyan with batt and full cart laying around somewhere and forget about it (sometimes for 2 days), while I'm vaping my 510s. I could never do this with my 601.
