I liked them at one time also and they are the reason I don't use standard cartos.
I had a issue with the draw being to stiff, but the cracking bases was the deal killer.
I switched to CE2 clearos (revision 6) since they have a more durable shell, but the wife hates pulling seals to fill.
The new CE2+ clearos from microcig are suppose to have the easy fill system and I have a pack being shipped to try.
I also like the new CE3 clearos from MiT (not smokymizers), they are bottom coil, but require a syringe to fill.
So yeah, I need my clearos also
If you do replace the top seal, you will have to pull the top metal ring. Some were tougher to get off than others and I used channel-lock pliers with tape on them so I wouldn't scratch the ring. I had a few that pulled off by hand, but they were far and few between.
Your setup looks just like the wifes, is it a pink KGO?
Edit: When I put the top ring back on, I folded a small towel and tapped the top ring until it was fully seated. Also, from time to time, check to make sure the top ring is always seated down. I over tightened the tip once and the metal ring popped up. I had one leaking, pulled the bottom seal up so it would make contact with the tip and this opened up the wick area to much which allowed juice to bypass the wicks also.
Once I noticed this, I tapped the top ring down and life was good again.
Food for thought
Hope that helps

I like it despite losing the little seal
the one WITH the seal doesn't leak at all and it's easy to fill, change flavors and I like seeing how much juice I have left too. It's a good, clean taste. I'll stick with them and be more careful not to lose the seals again.
