They tend to be not great from my reading.
You're likely better off going with JBD or ANT BMS. Both are on aliexpress.
For questions about component-level electronic circuits, tools and equipment.
1: Be nice.
2: Be on-topic (eg: Electronic, not electrical).
3: No commercial stuff, buying, selling or valuations.
4: Be safe.

Hmm ANT does have better documentation and differentiates between peak current and continuous current. They look more genuine.
Yeah, they have models with active balancing too for faster balancing.
I have the Overkill Solar JDB BMS and it's awesome. I've been using it every day for the 4S pack I built for my van. The Overkill Solar app is really nice and I believe it works with any JDB BMS even if you didn't buy it from them.
All these BMS seem more designed for high amperage solar system storage, generally using LFP batteries. I'm sure it's possible, but it seems like overkill.
Also Li-ion is not something I would keep in the house, especially a home-built pack. There's a high likelihood of fire. I built myself a battery pack with the same sort of cells, and a few weeks in I happened to walk into the garage when the pack started spewing flames out the side. They can be touchy and definitely need temperature sensors/current control.
