Yes, as far as I know that is correct -- both in TC & wattage. I have the Wismec Sinuous Savage & it has a 15 sec. cutoff which is a perfect length for me. The one wilky mentioned appears to have a side fire bar like mine which I love. The only plus of mine, for me, is that the 510 connector is centered. I like symmetry.
I didn't even know that it had a 15 sec. cutoff until I had it in hand. Unfortunately, this spec is usually not listed & if it is it's usually 10 sec. The reason I went with the Savage is because I can use Red Panda with it (Arctic Fox for color screens) & sur_myevic for cruise or autofire, although, to-date, have only used wattage.
