I agree with those CE2's. They're cheap and really really effective. Great TH and vapor from them. I love it. Taking the rubber plug out as he says makes a world of difference but they can leak a bit without it in. Just have to be careful with it and keep it upright. It's one of my favorite "at-home" clearos since I keep it upright but I can vape on that all night for how well it hits. I have the Xl version but the smaller ones should do just as well and give you a cheap way to test flavors with a very good clearo.
That or buy drip atty's to use on a twist or something and direct drip the samples.

The .9 small vision clearo are great easy to clean hold just enough to try flavors easy to fill. The small regular CE2 work great also i just take the plugs out and use just a drip tip.
