I was curious as well without forking out too much. I bought a Kmise KMU30B baritone ukulele (Amazon reference no B07HJ3GVL6) last Easter.
It is the only baritone I have ever played, so I can't compare it to others. It plays well, intonation is spot on. The action at the nut is higher that what I would like, but it doesn't reflect in sharp notes. The looks are simple, plain if you want. But is is very well-built and super tidy. You don't get a lot of other extras, except for the strap for the installed strap buttons, the gig bag (not very protective), some picks, and the key to adjust the truss rod. It's not a bad bet, I think, if you go for a cheap, functional baritone. Mind you, I can't speak for their GCEA tuned baritone, I was sure to stay clear of that.
It sounds quite boomy, it has a nice unoffensive tone. The strings were a bit disappointing for me. D and G were round; I don't like the noise. They are D'Addario, but the G string broke after about 5 weeks. The rest of the original set are still on. I play it about once a week, and I'm getting better with finding the correct chord shapes for the tuning.
