Almost everyone starts with clearomizers
I started vaping with Kanger T2s and T3s on an eGO stick.
First and foremost, Donimater, do not give up. A lot of us can relate to the problem you are facing. We've gone through that. You are new to vaping and there's a learning curve you have to go through. Eventually, you will begin understanding your device with your experience. In order to guide you in the right direction, it is important to know a few things:
What kind of eLiquids are you using. Is it VG? PG? What ratio?
How do you vape? Do you take single drag or double-drag thing?
How long do you hold the fire button while vaping?
Juices/Liquids: If you are using a VG (or higher ratio VG) liquid, you will run into the problem of burning coils and wicks
VG liquids are thicker and don't wet the wick properly. You may end up getting a burnt taste. I have used Kanger T3s for a long time. The coil/wick in T3s are at the bottom and the wick gets enough juice. In case of CE5, the coil/wick are on the top. So, your wick has to work extra in order to pull the juice/liquid. If it is a thick juice, you will burn the wick more often in the beginning.
Vaping Style: Seriously, it matters a lot! I did the same exact thing you are doing right now. Holding the fire button for long time. In the beginning, I thought, it is just gonna be like a regular cig and was taking single drags. But that didn't work. So I learnt somewhere about the double-drag thing and was holding the fire button through out the time! Ended up getting ...... about the burning taste. What you should do, put the tip in your mouth and press the fire button to take a drag. Just before you finish your drag, release the fire button so you suck out all of the vapers. Then you repeat the process making sure you don't hold the fire button any longer than necessary.
And there are many other factors in case of top coil clearomizers for example, hold the thing upside down in order to make the juice flow to the wick and then vape. Try it, will only help. I feel, you are using a VG liquid and that's why running into the "bad taste" issue.
If you just wish to stick to clearomizers, I strongly recommend T3s .. they are awesome! Check my blog entry from the left. I wrote a lengthy article describing how much I hated it but with experience, I just love it!
If you wish to try something advanced, the question is, how advanced and how expensive? You can jump on the Reo Grand bandwagon lol. But that is going to put a hole in your wallet! Not really! If you buy 20 other products and then buy Reo Grand or something else such as Provari, etc, "then you will put a huge hole in your pocket" ... know what I mean?
For me, my latest love is Rocket RBA from FastTech.com .. it is soooo good that I can almost write a book on it
My favorite MOD is Rob's ThroatHit .. It is a dual 18650 variable voltage brick. I love variable voltage devices!
Hope this info will help ya
