Lol, "light" is a matter of opinion and varies with your build. That said, they aren't light to me.
True, flavor is very subjective and really depends on build as well. I haven't found them to be light in flavor at all, some like Mech Sauce are very rich. I tried a few from them, most were good and most needed a good steeping to get the full flavor to come out.
Empress milk and Mech Milk were both good.
Area 51 was pretty good as well.
Smurf Murder was OK, I didn't like it as much as I thought I would
Medusa Milk is good, but I like using it to mix with other juices, especially with Butterscotch or coffee juices.
Mech Sauce is very good, but very rich especially with some steeping.
Crust is very good as well, probably my favorite from them.
Cyborg Slime was disappointing. I thought I would like it, but it had an odd musty taste.
Cosmic V was disappointing as well, just didn't like very much.
Blue Tentacle was very good as well, probably my second fav from them.
For the most part, I didn't like most of them FOB and needed some steep time. I steep them usually 4 weeks or so before I vape them. It sounds like a long time, but I found it was worth it, the flavors really came out and needed the time to blossom. Area 51 was probably the one exception of the ones I tried, but still needed a week or two to fully come out.
Mech Sauce juices are pretty good overall and I definitely prefer them to Vape Wild and Mt Baker.
