This product works well, and it provides a good deal, especially considering the low cost. Effectiveness They do work well at relieving or reducing indigestion. Some may still have a residual amount of indigestion left after taking these, but for the most part, they are effective. Personally, I have seen good results from this product when using it to deal with indigestion. But on the other hand, I do not suffer from constipation, so I cannot say either way whether or not these are effective at relieving constipation. Ease of Use Personally, I would rather take a pill than a chewable tablet that doesn't taste that great. They are not necessarily hard to take, but the taste is still somewhat unpleasant, and they can leave a little bit of a dry powder, chalky taste in the mouth. The bottle is also a bit large (admittedly necessary for including more in a package). But the largeness of the bottle also makes them inconvenient for taking on the go, such as if one is going out to eat and then going to a movie or something afterwards. I usually find something smaller to take a few with me, instead of taking such a large container everywhere. Immediacy These antacid tablets do work pretty quickly, providing relatively quick relief of indigestion problems.
