Why does the Sidekick V1 heat up quicker

The SideKick V1 uses two batteries in series to get 8.4 volts.  This allows the heater to heat up much faster.  The SK V2 uses 1 battery that has much more potential power, but because it is 1 battery, it is 3.7 volts.  Even though the SK heats up a bit slower, it can run MUCH longer.

has there ever been a titanium attachment for the ssv eok kit?

Yes, the Silver Surfer may have been the first E-Nail on the market.  We had not seen one until years after the first SSV EOK dab dish.   The heater had a titanium dish that one would put their dabs into.

Later we found out that TI oxidizes very fast at a high temperature and can become brittle after time.

The new Dab Dish is AMAZING
