I ordered these tetrahedrons to replace my existing ones after painting my helmet. I chose these as they looked similar to the ones I purchased from thefirestore a few years back. When they arrived, I quickly noticed that the quality was not the same. The tetrahedrons were thinner and there was a line running through the last one on the sheet making it unusable. I started applying the them and found that two of the seven usable tetrahedrons would not stick. In the end, I removed all of them and purchased a Scotchlite set instead. I'm not sure if I just received a bad batch, but it was enough to make me switch to a different product.

First thing I noticed about these tets was that they were more orange than yellow. (I ordered the yellow set - and confirmed with the affixed product number that they sent me the right set.) They are also not a solid color - they have reflective strips criss-crossing each sticker - which make them highly reflective, but they just won't work with my department. (The strips on mine are more yellow than the background.) Seem to be of VERY high quality - and very reflective, just not quite what pictured.
