I was surprised to hold this guard in my hand, it was very light, compared with a generic Union Jack guard that I have right now. At the same time, it seems to have some strength as it just needs to be strong enough to stop small rocks etc.It has some amount of flex but thats not a problem. The packing could have been better, as it was bent by the time I received it. I had to force twist in opposite directions to make it straight but it havent gotten it all the way, but eh, that should work.
