power curve

hey all, Are any of these mods that connect Bluetooth to your phone worth it ? Do you use it a lot? The only feature appealing to me , from limited research, would be ability to adjust Power Curve (for mods that have it) on the fly on phone - are there any other features that you use...

Wow - just received voopoo drag that has power curve feature of setting power for each second of vape. It's pretty amazing. I despise Direct Lung Vaping but if set the power curve from HIGH to LOW it's actually pretty Good ! So those with mods that have feature which direction do you...

Hello, I threw away all my mods and gear recently. Only own 1 mod. Voopoo is on order in mail and will be the second mod. The power curve options and the super fast ramp up time interested me the most. I realize it may not be the latest greatest but is it still decent.? Thx
