Really nice

Absolute rubbish. They don't turn on reliabley, the switch (which is near impossible to locate) stays down so they persistently turn them selves straight back off once you've managed to turn them on. Don't waste your money!!

Works ok

No instructions so had to work things out for myself... On the bottom, there is a 'click' button that controls it and makes the changes. One was fine and this worked well but it didn't appear to work on the other so I peeled back the black sticky base and then refitted it a little 'lighter' then could feel the click of the button. Long press is on and off, then just one press cycles through the static colours, then dimming colours. Quality reflects the cheap price but they are effective and work great if you're prepared to fiddle if your button is sticking, would buy more.

Works well enough no faults

You can’t turn them off unless you take them out the cup holder, and once there in the cup holder they are so hard to get out, will have to buy new ones waste of money.

Fantastic value for money 💰

They charged quickly and the range of colours are good, but they don’t turn off or come on as they are supposed to unfortunately.
