Compare rotary tool kits by the parts you will use

Pick two or three jobs the kit needs to cover. For a small sanding and polishing setup, list the band size, the drum to carry it, the polishing head and any required mandrel. Then read the contents model by model. A broad starter case makes sense when those holders and working ends are present. If you already own the holders and mostly run through one grit, a documented refill pack may serve the job better.

Separate consumables, reusable mounts and distinct profiles when comparing piece counts. Ten copies of a disc can be convenient for repeated work, while a few distinct head shapes can be more useful for mixed repair work. The headline count on a case does not tell you how the pieces are distributed. Compare the contents from the exact kit model and keep look-alike cases separate.

What is the first thing to verify when a kit claims broad compatibility?

Start with the tool model and the shanks of the included mounts. Then check which accessories each mount accepts. If the listing shows several collets, check which of those fit your tool. Use the kit contents to make a short list of the parts you can actually use.
