So far only used the one but it works great once it is heated, and it stays heated quite a while. I find it best to load the coil, then preheat counting to about 60 seconds, I then begin to lightly pull and get a nice thick smoke I can hold the button or release it depending on the amount of smoke I am getting and or can take! So if you want some heat and some big clouds I recommend these coils way over the one that comes with the unicorn device it just seems to heat better, longer, and more consistently. If you want to blow clouds with the device you have I recommend using it.
Gear is GREAT........................ BUT SERVICE SUX. One week just to get my order out the door then more than a week to arrive. Lookah uses the ABSOLUTE SLOWEST DELIVERY SERVICE WITH NO OPTION FOR QUICKER.
SPEND YOU MONEY AT THE LOCAL VAPE SHOP! IF YOU WANT TO SEE YOUR GEAR THIS MONTH
Excellent product and customer service. My device arrived with a little crack in the glass so I let them know and was immediately mailed 2 replacements! I felt heard and understood!
