Cheap light and tangled on first swing
This is tiny, cheap , plastic ! Ended up in bin after less than an hour as tangled very easily and broke when trying to fix. Utter waste of money.

It worked perfectly
It was much smaller than imagined as I did not take note of dimensions show but fine all the same.

A £10 gift that feels like a £5 gift at best
Feels cheap, base is poor quality plastic. Doesn't maintain momentum very long. Bought for my partner for Christmas as he loves physics but quietly disappointed in the quality

Cheaply made, but a cheap purchase.
Feels too light, but does what it should (just not very well) I got too experimental and it got tangled and binned. Buyer beware (you probably know but I didn't) its small and plasticy.

Cheap and arrived broken
Utter crap! Arrived with one of the strings not attached to the frame. Flimsy plastic and strings simply glued on.

Cheap and nasty looking.
Shocking the condition this item arrived, steal balls all tangled up. I would not recommend this item, and the price is ridiculous for what you get, definitely not worth it. Giving 1 star is to a higher rating for this product.

Kesinlikle tavsiye etmiyorum, bütün ipleri birbirine dolanmış bir vaziyette geliyor. Bir tane ip kopmuş haldeydi.

Auf den Fotos sieht es sehr gut aus (naja, ist ja immer so). Die Bügeln und Basis sind aus Kunststoff und einfach übermalt, gerade ausgepackt und die Lakierung ist schon an einige stellen abgefallen. Außerdem sind die Metallkugeln leicht magnetisiert, was den Elastischen Stoß beeintrechtigen und die Pendeldauer verkürzte, dh der Impulserhaltungssatz ist nicht erhalten... Vllt geht es mit der Zeit weg. Wegen Preisleistungsverhältnis muss jeder für sich entscheiden, die Sterne spiegeln meine Meinung wieder.
