There are no absolutes with the QLink. You can notice benefits that might range from the unbelievably dramatic to the extremely subtle. The best proof is your own experience. That is why we strongly recommend that, if your adaptation to the tuning of the QLink is too subtle for words, you remove it for a week after wearing it a full month. Taking the QLink off for a week after wearing it for a period of time is sometimes the best way to notice how you've been personally benefiting.
