Maintenance and proper use is all it takes. I clean my T2 heads about every 3rd tank. Doesn't take long to clean/dry burn and if needed scrape a little on the coils with a pin. I have several spare heads and may for some time to come. After 6 months, I'm still using the original heads and they perform excellent.
Higher power will give you an extra kick, but so will slightly raising you nic or lowering your VG. Also, increasing Draw time works. Liking the popping and crackling is just entertainment. Remember, every few heads saved is another bottle of
e-liquid paid for.
