I went with Touratech one, and it was surprisingly cheaper than OTR!
And for me it is nicer also, because of the fittings, the lines go better with it.

Downside is that it is attachet to the holes for windshield screen, those bolts needs to be metal ones, to be sure that wibes will hold that steel protector. But original bolts for windshield are plastic ones, so in case of hitting, you should brake the plastic bolts and not the windscreen.
Well when you have those TT metal bolts replaced with plastic ones, there is not the same case.
Hope I made it clear, since I am not wery keen with english.
I still like TT one better.

Here is mine:


Here you can see plastic and steel bolts. I would like to put plastic ones also for the protector holdings, but am afraid they will brake and I might loose the protector.

Hope this helps.
