I've got one. Works well! Reminds me to duck my bald head so I don't hit it on the edge of the hatch cover. That edge is sharp & has cut my scalp more than once! I miss the retractable cover on my Subaru WRX wagon. :sad:
Had to cut part of the storage shelf out to fit on over my subwoofer enclosure:
The cargo shelf provides some nice storage spaces for smaller items. Only downside is if you have to reach under it to get something further back in the cargo area, but that's a very minor issue. Also, the cargo shelf covers up the light in the hatch area, but I wanted more light anyways & installed a strip of LED lights to fix that issue. See posts about adding the LED's in the Appearance & Interior forum (may have to go back to 2010-2013 years).
