The Nalu RDA by Vaporesso is 24mm in diameter. It can support single or dual coil builds. The airflow comes in through the bottom. It is made out of stainless steel and Pyrex glass. This RDA comes with everything you need to use it atop your mod. It also comes with a squonking pin for added versatility.
The video reviewer displays the Nalu up close and demonstrates how to properly build on it. He points out some pros and cons with this RDA. Cons: O-rings pop off when no liquid is in the tank, and there is no adapter for drip tips. Pros: easy to build on, good quality structure, flavor is outstanding, airflow is good, and it comes with a squonking pin. Overall, he likes this RDA, but it is not his favorite. He feels they could have done a better job with it.
