Here is a wearable system designed to relieve your stress. Buzzies promise to improve your sleep, focus, and more. You get clips and attachments to use with them. Stainless steel Milanese loop watchbands are also optionally available. The companion app has 6 presets for you to choose from.
You will need a pair of these to get results. They use tactile stimulation to get you on the right track. Since we haven’t tested these, we can’t possibly judge how effective they are. More info is available here.
