I have the IVP D2. It is nice but seems a little hot on TC.
Have the Sigelei 75. I love my Sigelei as I own a few of them. They never skip a beat.
Do not have the Evic VTC mini but do have the big brother eVic VT. It is my favorite for Temperature Control. I think the eGo One Tanks that come with them suck. Leak like a siv. But the wife loves them and the coils are super easy to rebuild.
Stay away from the Aspire Pegasus until they fix the menu. Have not tried the version 3 which is suppose to fix the change over from watts to TC.
CHEERS!
