Impressive for its size

Pleasantly surprised by this unit. I have a larger diffuser unit which is good but as its big it stays in the same spot. This unit is the size of a coke can and easy to carry around and taken in the car, office, kitchen, bathroom etc. You'll need a USB power supply but a portable powerbank or PC/Laptop output is sufficient. The fragrance is provided by essential oils (not provided) but you only need 2 or 3 drops to last the whole day.

Pros:
Attractive wood effect (actually plastic but nicely done)
- Well proportioned unit - the size of a coke can and maybe a little lighter than a full can when the unit is empty
- Runs off USB so no hefty wall plug and can be used anywhere there's USB power
- Unobtrusive power connection below the unit - 1 metre bespoke cable is supplied as its only USB standard at one end
- Lasts a long time on just one refill and a few drops of essential oil - maybe 14-16hrs
- Can fill a medium sized room or a car
- Colourful LED light ring around the top to see it in the dark with various set alternating colours (can be turned off)
- Mist can be light, normal or on a 10s cycle
- Turns off if the water runs out

Cons:
Cant think of any to be honest but if I really had to think of something then maybe the motor whirring is perceptible when the room is quiet - but it wont keep you awake.
