Superb design and business practices I was delighted with the design and quality of the art and the way in which the transaction transpired. The product came from Europe and I was able to easily track the delivery to my son in Canada. The purchase was made as a metaphor for quiver theory in mathematics which my son is examining for his PhD studies. He was thrilled. What an outstanding design and service delivery

Amazing First off, the product is great. I've bought 1 for myself and 7 as gifts. Every single person I've gifted these to has been enthralled. Customer service,? I'd forgotten what that was until they emailed back, responded to my questions and helped me package 4 different colors so all the kids could get their favorite. No bullsh*t, probably the most helpful staff, best company I've dealt with online. And I've been doing this a lot of years.

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

Got it as a gift... Truly amazing! I got a Sapphire Square Wave as a present and I adored it from the very first moment! Truly a unique and unexpected gift... I keep it in my room on the stand and every time I pass by I can't help but giving it a spin. I could spend hours playing with it, it's better than watching Netflix! Plus, the manufacturing is excellent.
