Dropshipping is a fulfillment method. The kit is the product: a theme, a supplier spreadsheet, and a promise that the method is the moat.
That promise is backwards. Anyone with a card can open the same store. The scarce things are taste, paid traffic skill, and a reason a stranger should trust a brand that did not exist on Tuesday. The kit seller does not need you to succeed. They need you to check out.
If someone shows a store dashboard, ask what they spent on ads to get there, what their refund rate is, and whether they still run the store or only the mastermind. Silence on those three is the review.
