SALKING 500ml Aromatherapy Diffuser

This is the value-versus-benchmark call, and both carry a 500ml tank, so runtime is a near tie. ASAKUKI is the category standard - a slightly more refined build and the reputation that comes with being the unit everyone recommends first. SALKING delivers the same all-night capacity and adds a remote for less money. Pick ASAKUKI if you want the safe, proven default and will pay for peace of mind; pick SALKING if you've decided a 500ml tank is a 500ml tank and would rather keep the difference and get a remote out of it.

Different jobs. URPOWER is a compact budget unit built to get you to sleep on a small tank; SALKING is a large 500ml tank built to run past it. If your nightstand is tight and you only need scent during wind-down, URPOWER's smaller footprint fits better. If you want mist that lasts the whole night and don't mind a bigger unit, SALKING is the one actually designed for that - URPOWER simply doesn't hold enough water to compete on runtime.

More than it sounds. The most common late-night annoyance with a diffuser is that the LED is too bright once you're settled, or you want it off - and reaching a button on the unit means fully waking up. The remote lets you dim or kill the light and shut the mist down without leaving bed. On a big all-night unit like this, that convenience is the feature that separates it from a plain 500ml tank.

Only if you want it to. The LEDs can be dimmed or turned completely off while the diffuser keeps misting - which is exactly what you want, since any light in the room works against sleep. Run it dark and the 500ml tank still mists through the night; the colors are there for ambiance before bed, not a requirement during it. If a unit that can't fully darken is a dealbreaker for you, this one clears that bar.
