I actually enjoy this product. I have 2 melatonin ones. One heaven and one gummy bear. I also have a b12- sunberry & b12 + caffeine- watermelon ice. I have enjoyed the flavors, and the smooth energy without a crash as well as the night time routine of melatonin that aids in sleep. Already ordering more. 100% recommend! For a full and honest review, the only flavor out of all 4 that I dont really care for is the Heaven. I am not sure, perhaps I have a defective unit, since it doesnt pull like the other vapes. However I do enjoy all of the other flavors.
I have had my b12 sun berry and b12+ caffeine for over a week. And due to my level of usage, my sun berry lasted about the week. 800 puffs will go fast if you enjoy the process like I do.
