I quite like it but not enough to buy, and it's not toddler friendly so good for me.
I do really like the effect as I like burning Yankee candles/tarts but would find it non practical to use for any degree of time.
I'm sure a lot will become redundant within a few months and a dust collecter.
As for child safe not at all plus neither pet friendly, imobility friendly, poor eyesight friendly and without care poses a fire hazard.
The advise to add flowers to the screen I find totally worrying either fresh or otherwise.
