I bought a Cloupor t8 along with a tugboat. Every time I take the slightest hit I cough my .... off. I don't care for the tugboat at all. I hate the tip of it and actually pulled the tip off of my aspire tank to use on it. I'm not sure what to do. Any suggestions on what to replace the tugboat with? I bought the set up in a store and when I called them the next day they said I'd just have to buy a whole new setup! I can't afford to buy 20 setups to find one I like. I originally had an evod and just wanted to upgrade to something with a longer battery life. I think the store took advantage of me.
Any RDA (dripper) that you use is only going to be as good as the build in it.
Harshness like you mentioned is usually caused by either a hotspot on the coil, or your air flow is not directly lined up with the coils. Try twisting the top cap to make sure it is perfectly lined up. You might also try backing off the power on the T8.
If you like, give us more details including the resistance of your build, how much power your are setting your T8 on, liquid used etc. etc. Vaping an RDA is easy, rebuilding one too - but there is a little work in making sure it's safe and tweaking it to get the best vaping experience for you. Posting a pic would be super-helpful too (use imgur for hosting until you get 5 posts)
I think at this point, replacing it for another device without understanding why it's harsh just means you will have this issue further down the road. My recommendation is solving the issue first, then, when you are getting a good vape, deciding if you want to move on to other devices.
