Anyone ever heard of this piece? I have to replace the cover on my 12 bolt with something slimmer to clear a Watts link and am thinking about this unit. It looks pretty nifty and makes it really easy to check up on whats going on in there, which will be far more inaccessible after I install the watts link. I'm mostly worried about leaks as it does not come with a gasket as far as I know. Some off-road magazine did a review on it and said the thing couldn't be penetrated with a bullet and they were also unable to put enough weight on the thing to get it to touch the gears. They also said they could not get it to leak.
