As far as the results go, the sleep was very comparable. It was when it came to feeling leaner and the weight loss results where the effects just never seemed to shine like it did with UltraSurge. This is also a note that the marketing people at ReSurge seemed to focus heavily on so it was a little disappointing that it didn't deliver as well.
Overall ReSurge is a good product for achieving deep sleep, and worth trying if UltraSurge is sold out or if you want to do your own comparison. We found a discounted link that we have included below.
