Simket Rechargeable LED Armbands for Running(2Pack),Reflective Running Bands, High Visibility Light Up Armbands for Runners, Bikers, Walkers, Pet Owners

These are great and VERY bright. Fits around my calf perfect but a little loose on my arm. Waring them on my leg works fine and the cars can certainly see me. I use the flashing mode since I feel it makes drivers more aware. Nice that they are USB recharging and not batteries.

Etkili bi ışığı var oğlum için aldım akşamları parkta oynarken ya da dışarıdayken nerede olduğunu rahatça takip edebiliyorum

Die Armbänder sind schon geladen gewesen und konnten sofort verwendet werden. Das hat die Kinder sehr gefreut. Sie leuchten schön hell und erhöhen wie gewünscht die Sichtbarkeit.

La couleur verte est en plus très sympa.

these are fantastic! I love the recharging feature and they work well on my backpack while I ride my e-scooter. They are incredibly bright, thin, and take very little space when stored. The charge lasts a long time. Wish the company made little holes on each end so carabiners could be attached. I'd buy more to place them on other equipment/clothing for night rides/ walking.
