I am using rsst for few days now. It looks nice, but
1. Top cap get really hot ( 1.5ohm at 3.5volts )
2. Positive post isnt good for thin wires (0.2mm and less), hard to attach it
3. Airhole is tiny , too much vacuum
4. There is a little space between the base and the poly
tank. When assembled it doesnt bother
I am a little disappointed

I like cobra clone much better...
