Compared to the leading name brand products, it may not be quite as good. But a little less quality can be offset by a lower price. For the average person, this probably works almost as quickly and well as any product, so it can be worth it to give up a little quality in order to pay less. For the person with serious gas problems, he probably wants to pay more to find some serious help. Effectiveness For someone with extreme problems, the extra strength does seem to be more effective than the regular stuff. For most people, this product can be effective at reducing gas problems and the uncomfortable side effects that may come with them. Ease of Use I have never used a gas relief product that was easier to use than this one. Immediacy For some that have extreme gas problems and need more immediate relief, this probably is not the best solution, as it can take a little while to start working. But for the average person with average gas issues, it probably works about as quickly for them as any other, so it is pretty good.
