What the AI looks for in Men's Razor Blade Cartridges

Handle compatibility: Buy cartridges from the same system as your handle (Gillette Fusion family, Gillette Mach3, Schick Hydro, Harry's, Dollar Shave Club, and so on). Systems do not cross-fit. Each brand uses its own proprietary connector, so a cartridge that looks similar usually will not lock on.
Genuine stock: Buy from the brand or an authorised seller. Reject packs with blurry printing, missing lot codes or loose, unsealed cartridges. Counterfeit cartridges are common and shave noticeably worse than genuine ones.
Blade count vs. skin: More blades means a closer shave in fewer passes but more friction. Sensitive or ingrown-prone skin often does better with three blades than with five. Each extra blade adds contact with the skin, which can raise irritation.
Replacement interval: Replace the cartridge as soon as it starts to tug or the lubricating strip fades, rather than after a fixed count. A dull cartridge causes more irritation and nicks than any difference between brands.
Pivot and extras: Check whether the cartridge has a front trimmer blade, a lubricating strip and a pivot on the handle or the cartridge. These features vary within a system and affect detail work around sideburns and the lip line.

Gillette: Fusion and ProGlide cartridges share one handle family. Mach3 is a separate system.
Schick: The Hydro line uses its own connector. It does not fit Gillette handles.
Harry's: Cartridges fit Harry's handles only.
Dollar Shave Club: Subscription cartridges fit Dollar Shave Club handles only.
Dorco: Makes its own systems and some cartridges sold as compatible. Confirm the exact handle fit before buying.

Unusually cheap multi-packs of big-brand cartridges from unknown sellers, which are likely counterfeit
Generic cartridges sold as compatible without naming the exact handle model they fit
Buying a new handle system just to chase a sale on cartridges

Generally yes. Fusion5 and ProGlide cartridges share the Fusion-family connector, but Mach3 cartridges do not fit it.
