Review on Waterproof Aolyty Solar Strobe Warning Light - Super Bright 360° Flashing W/ Magnetic Base For Construction, Traffic & Factory (Green) by Knate Scarpelli

If you've thinking about using these, you'll have to wait a day to use them. What a surprise! They aren't useful.I thought these would be useful for traffic control in emergency response: I'd put them in places to get drivers' attention in advance of a control point. It turns out that you can't turn these off. So normally, I'd have these stored some place (and charged) ready to go. But not so: they will NOT be charged. So the night I decide to use them, I won't be able to use them, I'll have to charge them the next day, and then use them the next night.Or, I'll just leave them in the sun all the time, except that they light up and get discharged over every night. And am I supposed to leave the lights flickering some place every night outside?Truly, an idiotic design.
