So I bought this hoping that it would be less maintenence than just a standard wax vape but it wasn't. It's the same amount of maintenence that any other wax vape is. The Nero technology coil barely even hits. I wrote Yocan asking them about this and never got a email back which means I will never buy Yocan again. Battery life sucks get only about 15 hits before it has to be charged. Charging time is quick however with it charging in about a hour. The dual coil hits good but u better plan on having to clean it after every ten hits because oil gets all over no matter if you fill it all the way up or only put a little bit of wax. Don't really regret buying it but probably wouldn't buy it again....
