Love it, flawless. The free screwdriver that was included fits the post screws much better than the one that came with the device.
This thing is amazing!
If you have a spare mod with great TC then I would recommend. This is very different to the buckets. It is fast and easy to glaze the hot donut and the resulting hit is instant. Subsequent hits are instant as well and you can keep on loading and hitting with no swabbing needed.
These coils taste better than the Yocan and Sai donuts. But like them, there are reclaim issues that build up and initial seasoning can be a bit rough.
So buckets offer better taste and efficiency. But sometimes speed matters. And at this point it's just a case of trying them all.
