Cliffy, I'm pretty sure those are old pics under the v3...
Perseas, I think the link from the updates page for the Spheroid v3 is incorrectly pointing to the upgrade kit. Also, do you have a general idea when the 510 adapters will be available for the Heron?
Thank you, I corrected the link!
The photos will come in the next days. The 510 connection for the Heron is almost ready and possibly will be available on Vapourday, but I kept it out just in case something goes wrong at the last moment.
