IEGreat product but overpriced IMO I really like the BETA product and have used SIS for many years with varying results. I think the beta product works particularly well for me (no stomach issues and more palatable than the likes of Morton) but if you cannot avail of a discount, i think it is too expensive. It is difficult to justify the price given the alternatives you can now get and/or make. However, if price isn’t an issue or you want to splash out ….. all thay said, these products seem to impact stomachs differently so always test pre important event etc!
