anyone know anything about the ATTY cubed and i was thinking about getting a RX200 as well
I have an Atty 3. It was my first dripper. It's in my obsolete box now. In my opinion its 4 post design is a PITA to build on compared to a velocity deck. 24 gauge kanthal is doable, but with Claptons it's nigh impossible to trim up the leads when installing the second coil. The way they're positioned means that the leads for the second coil are crashing directly into the first installed coil, and you need super slim clippers to trim up the legs. It's also a pain to get the coils positioned evenly. They're supposed to sit off-set, but they tend to end up way too close to the edge, requiring a lot of tweaking to get them evened up.
The screws on mine were constantly loosening up. Not stripped, just always coming loose. Additionally, the funky air slots make it prone to leaking. There are far better designs than the Atty 3. My favorite dripper atm is the Mutation V4s (velocity deck), but a standard Velocity clone will also get the job done.
