TLDR: Re-Chargies are fantastic, but I had to dock a star because it's a small amount of product per tin, and in practice the cost per use ends up steep. Details: These are a godsend for my chronic, hard-to-treat insomnia—there are a lot of products out there that aid in falling asleep, but I've never used a non-Rx product before these that actually helped me *stay* asleep (which is the issue my variant of insomnia causes) all night. Extra impressed that they can do this and also be truly non-drowsy. Great for bedtime but also for taking the edge off, simmering down after an intense workout, etc., at any time of day. The downside is that, at 20 gummies per tin, you're getting only a few weeks' supply if you use them regularly, or less—taking two gummies is more effective for me, but that leaves me with only 10 servings per tin and a high cost per serving. Even if I ration it to one per serving, less than a month's supply per order means that to stick with these I'd have to re-up quite frequently. Ultimately, I avoid using them as often as I'd like to. All in all, amazing product for daily use with a range of applications, but a bit of a disconnect between practical usage and packaging/price.
