Review on 🚴 NiteRider Sentry Aero 260: Powerful USB Rechargeable Taillight for Standard & Aero Seatposts by Michael Dixon

Great rear light for day and night! I only use it in the dark, but it's super bright! Many modes from flashing to solid are available and they will survive any headlight. The battery lasts long and charges quickly. I only use it for a few hours at a time and I'm barely scratching my life. I always have to charge my headlights after every ride, so I charge those too, but I could probably drive 15 times without a charge. It comes with two straps of different sizes that can be attached to the seat post. Easy to turn on and off, only use in the dark. Very happy with the purchase and will definitely buy again. No regret.
