Well after weeks of use my atomizers are getting harder to draw on like everybody else I clean, blow, align the holes in screens behind bowl witch helps for a short time, then I got a new starter kit Friday with the 901 model witch had a nice easy draw and lots of vapor so I looked at the difference between them and the 901 had a slightly bigger hole on the atomizer housing! I grabbed my variable drill with a dremel bit as shown in the picture and very slightly enlarged the air intake hole8-o (still a little smaller than the battery inlet) and it performs absolutely superb so I did it to my other 5 and all work better than new !!!
Now for my own take on coil burnouts , if their is not enough air flow through the atomizer during operation the coil gets over heated all the time shortening its lifespan!
Here's some pics of the new sized hole and the tool used, try it on a very hard to draw on atomizer first so you don't accidentally ruin a satisfactory working one ,Its real easy and real fast Good Luck!
