Good product. Just what I needed.
Enough for a Petzl Vertex Vent helmet. Fortunately, there will be spare tapes that can be immediately cut into another layer of tape. Otherwise, the tape will not adhere properly to the lattice portion of the bracket. It is difficult to estimate how the bracket with its luminaires would last in use without decoupling.
Attaching a cycling helmet with stickers is tricky. There are so many vents in my helmet at least.
However, this is needed if you want to use Superraptor.
If you use cable ties, then you can do the same to the superraptor directly.
I returned back in vain.
If you have a construction site helmet, then this is probably really working for it.
The bracket is ok. The helmet only is designed so that the bracket is not the best possible for it.
