Could have been a more robust structure

3.0 out of 5 stars Good but cheap plastic

Was good but plastic was cheap

1.0 out of 5 stars Waste of money. Not scientific. Doesn't work.

What a waste of money! All is plastic. Nothing scientific. I could buy a similar quality product from Poundland. Doesn't work-tried 3 different well-branded batteries. Sent with out a delivery box or wrap. So all the delivery labels were on the box and couldn't wrap it up as a present. Disappointed for £25.

Crap

2.0 out of 5 stars Came scuffed, was not impressed

L.N. · 4 April 2022

Metal was scuffed and had lost paint, battery holder broken. Was advertised as “great condition” but I’m forced to believe otherwise. Would love to see in action but it’s broken… if there’s some way of acquiring a refund please feel obliged to contact me. I am enraged at the matter and deserve justice!

Great Science Fun - Value

Simply one of the coolest items for the money I have ever bought. Tons of energy from one 9 volt battery and magnet.

Very nice toy.
