Review on SMALLFATW Portable Emergency Light 15” 12 LED 9 Flashing Modes 4 Powerful Suction Cups, Super Bright Mini Visor Strobe Light Bar, Dash Windshield Warning Light For Vehicles Car Truck, Red&White 1PCS by Tim Hollins

Works as described. I put it in the back window of my suv, as close to the top as I could get so it wouldn't block my vision. It took about three days to get the suction cups to stick. I took them off the light and still had a hard time getting them to stay in place. I cleaned the window several times and put windex in the cup itself. After they stayed on the glass overnight, I removed them and put them back on the light and amazingly it has stayed attached to the window for over a week on terrible bumpy back roads. I've used the light for hours at a time and nothing has burned out. I'm a rural mail carrier and got this as a back up to the official US mail roof light because in the full summer sun, you can't often tell the lights on the sign are blinking. I'll try to update in the winter as I'm out delivering after dark frequently. I'm concerned they'll reflect off the inside of the window and make it hard for me to see behind me.Edit- 1/3/2020Still works fine, having it on after dark isn't bad. It reflects off the lower part of the hatch, below the window so I can still see to drive and not notice the strobes in the rearview mirror. The suction cups are not great and I have had the light detach partially from the glass where I clean the glass and re-wet the cups to attach them again. I've also had it completely fall off the window. I have a shelf in my suv so it only fell a couple of feet instead of to the floor, but it still works. Overall I'm happy with it
