I purchased an ego XL around xmas and cleaned the attys last weekend after just using periodically, now my favorite does not work, it shows resistance to 7.0 and climbing, is this garbage? the other atty is 2.6. I have had a heck of a time with these, my other atty was tasting burnt right off the bat which I figured I did not prime it right and I have not go the hang of the carto's yet. So far all I do is drip, man I hope this is not dead, should I try and debridge or dewick it. I did purchase a few more attys last week to have extras, so much for extras.
