I love the blue L.E.D. ring! but not the stainless steel rings that hold the front to the back which I found very fiddly to refit! The bulbs are also a bit overpowered, so I don't use them continuously because of the power drain. I may look for some lower powered bulbs to fit.
What's not to like? It serves its purpose very well. I like the mesh because a Perspex visor would get scratched and opaque, and it works just as well and is possibly lighter. the ear defenders swivel up onto the helmet when not required. I also use the helmet and visor when chopping the wood - just in case. Good value, should last for years.
