Anyone own a Site Lite Mag laser boresighter?

I had some Cabela's gift cards I redeemed a couple months back and used them to buy a Site Lite Mag Laser bore sighter.  It was on backorder for a long time and I had forgotten about it until it arrived today.  Looking forward to moving around some scopes and adding a new Leupold to the collection and hoping this tool will help reduce time at the bench getting rifles to zero.  Any reviews?  Would love to hear what others like or don't about it, tips, etc.
