Wong Lo Kat is an excellent product. It is a sweetened tea beverage, much like Thai tea without cream. There's really not a whole lot to say, I suppose. It's a Chinese herbal tea...sweetened...in a can. It's quite delicious, and very refreshing. It tastes very clean and the tea flavor is pretty much intact despite being packaged, which is something on which American manufacturers need to get a grip. I hate packaged (bottled, canned, etc.) tea over here, and I don't understand why we can't seem to make one that doesn't take like chemicals and preservatives.
But Wong Lo Kat is very good. It's a little on the expensive side (about a dollar a can, even in six packs), but it is well worth it. The can is of high quality and feels good in your hand, and the drink itself is light, refreshing, and flavorful.
