When using the 510 mega cart and atty I've noticed it will start to tast burnt long before all the juice is empty.
Easy Solution: Take out the polyfil and you'll notice the atty end on the polyfil is much darker. Just flip over polyfil and reinsert. You may have to add some drops if you squeezed out some of the liquid. It may also help to add a few on the atty again. Then just keep on vaping! Hope this helps
