Price, Quality, and they work.
Wanted to try with or spending a fortune. They work, great nights sleep - used then 2x this week. I did not wake up feeling groggy like some sleep aids. Some sleep aid meds have me bizarre dreams, this did not. Great price and was hesitant but I'm impressed with The Amazon Basics line. I tried several products and feel great in a week.

Tabs work 100 per cent
Product worked well for my system. A bit too well. I took a whole tab the first night and l was out before planned. Too 1/4 tab the second time and it felt more natural.
