It gets hot as fuck, thats not the problem. It leaks/eats more oil than fucking 5 standard carts ever could. Which sucks because thats why i bought it.What's the issue you're having?
If you're using oil it requires a warmup period at 7.4v to transfer enough heat up the oil tank to melt the oils.
If your using flower you remove the oil tank and put your ground herb directly around the mini hammer.
It must be used will solid red IMR batteries, lithium ion batteries like Trust Fire won't work either.
Does your Herc get hot? Is your Persei working at 7.4v using standard carts?
Does anyone know if there is a high temp solder that would work for clogging the leak? You could drip it hot into the heater base where it would solidify wherever the oil is going. Would this be safe or just void my warranty lol?
