Square Wave for 5 year old! Bought the square wave for my son’s room. I told him he could use it to help relax before going to sleep. He’s extremely sensory seeking and it has worked like a charm! The wave keeps him entertained and then he goes to sleep peacefully without coming out the room 20 times. He loves it and plays with it often. Totally worth it. Thank you Kinetrika!

Ordered mine in May - it's still not here Ordered mine in May. Still not here. The customer service is non-responsive. Very disappointed.

Perfect gift for civil engineers I saw an ad on Facebook for the Square Wave art works and found them very beautiful and fascinating. I ordered a three pack in silver, gold and dark bronze colors for myself, my mother and my sister and her husband. My sister's husband is a civil engineer and he immediately fell in love with it and took it to his work to show his coworkers. It was very fast shipping from Italy to the US. The packaging was flawless and the art beautiful. Thank you so much. Amy DeLong.

Buyer Beware!! I was not warned before placing the order that the items would be sent from Italy and a Customs Charge would be levied. I have had to pay £54.95. I was informed by Parcel Force that I could refuse the parcel which would then be sent back. Atellani told me they would not make a refund of £231.00 which I paid. ‘Buyer Beware’ the costumer protection we have in U K does not apply when dealing with foreign companies. I successfully returned an item to Stella Mc Cartney, Italy. All credit to them. A reputable company.
