We run Cat's Eyes on about 600 tractors and on most of the 1500 or so trailers we have. We tried the Crossfire units, didn't like them as much and have settled on Cat's Eyes. They have some potential flaws you have to be aware of. Make sure that you make a habit of checking the connections from the Cat's Eye to the valvestem. I have had them work loose and deflate the tire for me. Only one deflates, since the system does keep the tires separated.
On tractors with Alum wheels, we take nylon straps and strap the hoses in place to the hubs, which prevents them from chafing and rubbing on anything and prevents the hose from uglying up the aluminum wheels.
They do simplify daily checks, but you still should gauge things once a week or so.
