Petlibro Luma review please

I've been looking into automatic litter boxes for a while know and keep going back and forth. Originally was set on the Litter-Robot, but the price is kind of hard to justify rn.

Recently came across the Petlibro Luma and it seems like a decent alternative, especially since it's about $300 cheaper, more open on top, which might be better for my cat (he's picky with covered boxes), and has most of the specs of LR 5.

For anyone who's had experience using Luma, how has it been long term? Mostly curious about reliability, how well it actually auto-cleans, and if your cat adjusted to it easily.
