Yup, I checked antigravity gear site and am surprised. $29!!! It's only 1900 yen in Japan, at current rate $21. So I hope it includes very good English manual.
I've done a little comparison test.
Side B boils 300ml water in SP450 at 15 temp/ room 20 temp centigrade in 6.5 minutes. Took 40 sec to blossom.
MBD Atomic boils 300ml water in SP450 at 15 temp/ room 20 temp centigrade in 5.22 minutes. Took 30 sec to blossom but with pot on.
I used T's stove Titanium pot stand with Atomic, 2000 yen.

You can see that Side B makes very beautiful flame that fits nicely to SP450 bottom.
Some may think Mini Atomic would produce better flame. But Atomic's bigger diameter centralize flame better and does not make handle too hot but boils water efficiently for SP450.
