I've written this review for another lamp i purchased, but it is exactly the same as this one which I also purchased
As a lamp, it just does its job, but as a lava lamp it does absolutely nothing.
I bought this for my daughter, and it cost me thirty three euros.
It's not even worth fifteen.
The bulb has been changed once so far, (the exact same bulb as in the manual, R39, 35w mirror bulb, not LED) and you can leave it on for a whole day, it does absolutely nothing.
The wax sits on the bottom, and the fluid is hot.

Just incase someone thinks i have no idea, i had a original lava lamp, from the UK, which cost me €110, and it's been working perfectly well for two years now.

These lamps have been imported from China,
And are not worth anything,
Don't buy.

I wanted a lava lamp for a long time. I am very satisfied with this one, I can't stop looking at it. The lighting is not satisfactory as expected since they are not made for practical purposes. The glass container contains yellow wax and blue liquid, but when you turn it on, it has different colors than the picture (blue, purple, green, yellow, orange, pink, red) (yes, all of them), which personally doesn't bother me.
