First you gotta love the slogan. "ModKat: Where modern cats do their business". Also their logo, which is reminiscent of Azure & OneDrive. See photo #1.
More importantly their litter boxes really work and aren't ugly. By really work I mean don't cause tons of little bits of litter to get all over the floor.
They make a model that's like a batting cage, open with a shield around it. It's good. They make a top entry only one too but for small cats and older cats it could be awkward.
The best one so far I've tried looks like a recycle bin with a folding top. The cats love it and I have 90% less mess and dust. See photo #2.
