Review on Fasmov Triangle Warning Frame Set - Pack of 3 Triangle Emergency Warning Reflectors, Safety Triangle Kit for Vehicles, Car Road Reflective Emergency Triangle Kit by Andres Imaging

As mentioned, they are very light. They are very easy to unpack and assemble and as shown in the pictures there are four small stabilizing feet to help keep them upright. The bad news: you're likely to get drained, possibly repeatedly, if you use them to break down at the side of the road. Passing traffic (especially trucks) creates enough wind to blow them away (which is very bad if you install them an adjustable distance from your vehicle). The rest works fine.
