Storz and bickel was a complete game changer for me. The quality and flavour are insane. I upgraded to the stainless cu with glass mouth price and stainless caps and it rocks. This unit is over 2 years old now and still as good as the day I bought it.
I've got an arizer solo 2 too and another small vape and a wolkenkraft aris ultra that I can't find (pissed about that) - the s&b takes the crown
From what I hear ball vapes are the next level up but I don't want bongs and stuff lying around so the mighty plus does everything I need and I would definitely recommend and buy again. They're warrantied for 3 years too, the new venty is very interesting but pricey.
The frolic vape is getting a lot of attention right now as it's got a replaceable battery (s&b don't) but you can't get stainless accessories currently. It's interesting as it's got a cooling unit too unlike the tm2 and hex.
Since I got the s&b I haven't combusted ag all and it's over 2 years now lungs definitely feeling better for it.
