This is a great concentrate. My only complaint is the it leaks. If I have the vape in anything temp above warm (like the car, my pocket etc..) it will leak and be sticky and wind up losing a bit in the end

Really great about keeping up to date on time of delivery.

I have gotten this same brand many times but it must have been a defective cartridge or something. Half if not more of the oil went to waste. Normally this is a great pen for daytime use
