I love my T3s and they're really durable: real solid pieces that I throw into pockets or purses or backpacks all the time without any problemos.
The problem I encountered was filling one with some newly received amaretto juice and that caused it to crack at the base and make a big deliciously smelling mess. Luckily I had it sitting on a table upright, since I had just filled it and was waiting for it to soak up the juice. After that I read the enclosed packing slip that informed me not to use amaretto juice (as well as citrus and some other juices) in plastic tanks. Sigh. Good thing I bought 5 T3s in a co-op, so I didn't weep at the loss.
I'm dubious about those metal T3s since they still have a clear window, which I assume is of the same material as the original clear T3s.
I want to enjoy my amaretto juice but I don't know how. I don't like cartomizers with fiber filling because either the juice I have is too thick for the small hole and I don't have a cartomizer punch, or I worry about burning the filling since I've done that before and that made me sad. I also don't like the bulkiness of any of the tanks I've had, which is why I like the compact streamlined design of the T3.
I've etched/clouded up other clearomizers (I guess they're some sort of CE something or others, top coils), and those aren't "rebuildable" like the T3s or ViVi Novas and such. I haven't clouded up my T3s yet, and I've used them far more.
I like the clearomizers that came with my iTaste, they're called Tidy Clearomizers or something, though these Tidy Clearomizers seem like they make dark juices taste burnt. I'm scared to try my amaretto and other new citrus juices in these Tidy's for fear of another amaretto disaster, but I really want to enjoy my new juices and I'm not looking forward to a vaping spending spree.
What do I use to vape juices that almost instantly break T3s? I'd like to be able to see the juice. I like the ease of T3s with their replaceable atomizers and great taste and vapor production.
