Problem with aspire coils burnt hits

In short, ive had 10 coils, 5 x 0.27 and 5 x 0.4, only 3 out of the 10 have worked.

Ive primed them all well, let it sit for over an hour, start on a low wattage, and yet the 7 duds have all given burnt hits and had to be thrown away. I feel this is unacceptable and am considering moving away from aspire simply because of their coils. When they work they are great but its so rare for me that they do.

I prime them well and have even taken them into a shop who told me i have got a bad batch.

What can i do?
