To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Despite trying to go bed early I just can't seem to doze off. I would often buy one-time use heated eye masks from the pharmacy to remedy my insomnia until I discovered this product. Simple to use - set the heat level and adjust the time duration. I check my Fitbit every morning (which grades my sleep quality and cycle) and I can testify since using the USB version it's improved my sleeping pattern. Also the aroma scent is a nice touch.
I have always suffered with dry/itchy eyes. Just using this 10 min at night before sleep has made such a difference with symptoms as well very relaxing helping me to go straight to sleep. Great for hangovers too...I will be buying this as a Xmas gift next year. Great value for money.
