Great, friendly and patient staff. They taught us techniques on how to properly coil an omega rba which we also bought from there. We also picked up a chi yu mod, an origin mod and a nimbus rba a while back. Even though the mods are clones, they are of great quality made by HCigar. They even polished up my gf's chi yu to remove the oxidation for free and told us where to get the supplies they used to clean it with. The nimbus rba clone they carry also has a drip shield while my other chimbus doesn't.
I picked up a Kayfun 3.1 also from HCigar. They showed me how to put it together and wrapped a coil step by step. Even a costumer stepped in and gave me tips on how to fill it from the top properly instead of using the side hole for filling. The kayfun is running great at 1.4 ohms. I cleaned it when I got home just to remove any extra machine debris it may have.
If you're looking for a place to buy mods and learn more about them, this is the place to go.
