I like the mar-boh alot!
I have had a couple of bottles that really had no flavor tho, even after sitting around for weeks-these were peanut butter cup and peanut butter (ordered at different times), and they were double flavor too-even after sitting around-nothing, altho the aroma is there so maybe its just me-might try adding some sweetener and see if that does anything.
The apple had a strong apple flavor tho-and the ry4 was good, a bit mild on flavor but still good.
