The moment that sold me on these was standing in front of a kitchen drawer at eleven at night looking for a whisk, and finding one instead of the usual tangle of rubber bands, a dead lighter, and a single chopstick nobody can explain. An organizer, the plain divided kind, turned that drawer into something I could actually use without swearing at it. That is the whole pitch, really. It is not glamorous. It just works.
When you are choosing one, check the depth against the drawer or shelf it is going into, not just the width, because plenty of organizers are sized for a generic drawer that does not exist in most real houses, especially older ones with shallower joinery. Press on the dividers too, the cheap ones flex and slide around the second you load them up, which defeats the purpose entirely. If it is for a bathroom cabinet or under a sink, check it can handle a bit of damp without warping or smelling off after a month, plastic and metal do this fine, some pressed wood ones do not.
Where they go wrong is anywhere you want the eye to land, a coffee table, an open shelf in the living room, a mantle. An organizer in a visible spot just reads as clutter wearing a uniform, and no amount of tidy compartments fixes that. They belong hidden, behind a door, inside a drawer, on the inside of a cabinet, doing their job where nobody has to look at them. What they sit well with is anything else in that same drawer or cupboard that is already a bit mismatched, a junk drawer, a bathroom cabinet with four half used products, a desk drawer full of chargers and dead batteries, because the organizer is quietly solving a problem that was never going to look nice no matter what you put in there.
They suit every kind of home, honestly, which is rare for me to say about anything, but a rental with no storage gets more out of one than a house with built in cabinetry ever will, since you cannot change the drawers but you can absolutely change what lives inside them. Kitchens and bathrooms get the most daily use out of them, offices and craft spaces close behind, and there is no season to any of it, a junk drawer does not know it is July. The only real rule is to measure first and buy for the space you have, not the one you wish you had.
