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.

Ήθελα μια lava lamp εδώ και καιρό. Είμαι πολύ ικανοποιημένη με τη συγκεκριμένη, δε μπορώ να σταματήσω να τη κοιτάω. Ο φωτισμός αναμενόμενα δεν είναι ικανοποιητικός αφού δε φτιάχνονται για πρακτικό σκοπό. Το γυάλινο δοχείο περιέχει κίτρινο κερί και μπλέ υγρό, όταν το ανάβεις όμως, έχει διάφορα χρώματα εκτός της φωτογραφίας (μπλε, μωβ, πράσινο, κίτρινο, πορτοκαλί, ροζ, κόκκινο) (ναι, όλα αυτά), που προσωπικά δε με χαλάει.
