I have the Wasp Nano and liked the look of this so bought it as it was a similar design to the Wasp, but a bit bigger. After using this, the Wasp was retired. The airflow is much better as it's angled at the coils diagonally instead of hitting the coils straight on. This means the air covers the hole coil, not just the middle. So easy to build (you do have to remove one grub screw on each post, but that is no issue at all). Great, great flavour. I use this a lot as a squonk RDA.
