Seems durable, but the mounting system really is poor - you are better off mounting it with wire
Reviewed in the United States on May 12, 2020
This comes with little springs that are intended to tie the screen to the water heater grill (and the furnace exhaust outlet). The springs come with a little tool to install them, and the tool works fine, but two springs per screen seems hardly adequate to hold this on while driving at highway speeds. Bottom line - I threw away the springs and used some wire to twist from the back side of the water heater grill. This feels a LOT more solid to me, and this product would be better if it came with stainless steel wire to twist rather than the springs. The furnace outlet was a bit more tricky since there was no grill to attach it to, so I used the same idea and twisted the wires around an aluminum nail on the back side of the furnace outlet. I had to remove the entire furnace cover to achieve this (because the furnace outlet has to be screwed to the furnace cover), but that still worked a lot better than the springs.
This needs a design change to make mounting the screens a more solid solution. I'll give this 4 stars for now because the screens themselves seem to be a good idea and is solid, but the mounting system needs improvement. The photos are from the water heater installation - I didn't get any photos of the furnace, but it's the same idea.
