The tradeoff of quality and price must always be considered when thinking of buying an off-brand product. This particular product seems to be as effective as the name brand alternatives, but it costs less. Combining those two factors leads to a positive rating. Effectiveness This product is effective at calming the body and helping it relax, which can be great when someone is trying to sleep. Rather than simply being a sleeping pill that puts someone to sleep, it seems to work more by calming the body to help it relax and sleep. Ease of Use This product is extremely easy to use and take. Immediacy This product works about as quickly as any other equivalent product that I have tried. Some may not be happy with how quickly it works, especially if they struggle with falling asleep a lot. But for the average person, it probably works as quickly as it should. Side Effects Personally, I have not experienced negative side effects from this product. But some may suffer from drowsiness and lack of energy at times when they are not trying to sleep.
