Previous tip:
I got the ti helix tip sunset color to finally complete my H2. Wow is this thing a huge improvent in several ways. Airflow is greatly increased which I immediately noticed. The m+ tip was restrictive comparatively.
The speed to heat with induction heater is faster fue to lower thermal mass of titanium and the helix being machined to be the lightest weight wise. This means the tip allows for more efficient use of energy for more heat cycles per battery charge.
I like the helical twisty swirlies. The color was purple not reddish orange so I was surprised and thought they sent the wrong thing! It seems any amount of finger oil turns it from light purple to sunset tan orange. I think that's bitching I love color changing stuff and purple is my favorite color so I was happy regardless.
The holes didnt have noticsble burrs thats what I was worried about. It was machined to within my expectations, ran it through some ultrasonic alcohol anyways before use as is good practice.
