I am very satisfied with MBV. I was using their 50/50 @ 18mg The 236ml bottle last me about 2 months. I recently changed to the 80vg/20pg. I have noticed it mutes my flavor a little due to the high VG,but figured the pg coupled with my allergies might be making it worse. The vape cloud is great,but I prefer flavor. I have noticed my cough has gone away since going to the higher VG. I know I could buy vg,pg,nic and mix my own,but this simplifies it for me. I wish they would add more flavors to their DIY,as they have gotten rid of quite a few and that leads me to search elsewhere.
