lovely little thing, the blue bulbs look calm against our cream wall. Took a day or so to settle after I hung it up. Only reason it’s not five is that the tags are a bit fiddly to read at first glance.

Third thing I’ve bought from here and it’s another good one. Packed well, turned up quick and it’s pride of place in the hallway now. Bit pricey if I’m honest, but it’s a proper conversation starter.

Bought this for my grandson Alfie, who’s seven and mad about science. His smile when the little bulbs began to bob about was a picture. Lovely and simple.

Bought this for my grandson who loves things like this. His face lit up when he saw it. Said it was ‘cool’ and keeps checking the temperature. Kept him busy for ages figuring out how it works.
