The top broke off on of the cones on the first day after tipping over. It wasn't thrown or abused, but simply set down off balance and it tipped over and the top was so brittle that it broke clean off on impact.
We upgraded to these for one of my wife's trucks. Great quality. Correct size for compliance. Heavy base for stability. Very pleased with the products. Highly recommend.
The white reflective is simply slide over the cone and slide off when separating the cones. I will be using them with horse training and riding exercises, so I suppose I will not need the reflective portion.
The cones are extremely sturdy.Only thing is, if you stack them the tape begins to peel away. Simple to replace the tape though. I would recommend and purchase again if needed.
