I had the same experience with the CE clearos. I highly recommend you try out a EVOD on your Spinner. I use it all day at work and never get a burnt taste. I usually use a 70/30 mix in my EVOD. I do realize that the EVOD uses the same coils as what you put in your KPT, however I can only comment on my experience which has yielded great results.

ps.... Don't vape too fast
When buying ego type batteries I recommend only buying genuine Joyetech or Vision batts. They both are made with over charging and short circuit protection in the battery. I read through a few of the exploding battery stories and it appears they were using off brands.
eta...... beware my opinion is biased
Sweet-Vapes has some nice kits put together. There juice is fantastic also.
