I haven't tried those 2, a few people on here seem to rate the pinkman, personally I like spectrum vapes pinkman concentrate, it's 5 quid for 30ml and tastes great at 15% ,
20 quid for free postage so not like you have to break the bank for it if you chuck in 3 more concentrate flavours. I tried unicorn blood and rainbow sherbet from VRU, both bland unless used at 20% so cost wise for me it just doesn't really work out.
Also tried Refreshers, ok at 15% but was just burning my coils and got boring quickly.
But yeah apparently pinkman is ok.
