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

Now I've ruined two of these lights by just taking a single ride in the rain. The first time I thought the little plug was fully inserted into the USB port but it was pointing down so I thought ok my fault I'll buy a new one and make sure it's fully closed and pointing up. nope A ride in the rain killed him again. The problem is that water gets into the lantern. Causes a short circuit which causes the light to turn on and stay on until fully discharged. I can't figure it out. Don't shake, don't leave for a week. The light is useless now
