My dropdowns from AGS/Apollo arrived. Quality is good and and feels solid enough. I noticed at least one of the joints is ever so slightly off but it's maybe only a degree or two and I can live with it. The other one seems straight. I tested the airflow on all my pieces with them and noticed with my OmniNail it's gone from slightly restrictive to just right. Works especially well with my OmniNail and Diffusion Pump.
My Domeless.com nail and carb cap is taking longer than DHGate at this point, took a week to go from WA to LA and it's been on its way to Canada since last Monday night. Hopefully it will be here this week, can't wait to try it.
It's a bit pricey especially with the currency conversion but I'm seriously thinking about getting
this setup. The nail has a deep curved dish surrounded by the coil, has 16 air holes and it uses a custom titanium dropdown in between the base and the head. Not sure if D-Nail heads will work but even if it you're limited to their heads you have a dropdown that will never break. As a bonus it has a removable reclaim container that can be used in a future vape pen they've teased a few times.
