5,145 Backers, 182 Reviews, Zero Complaints, and Half a Point Short

Five thousand people backed this on Kickstarter. One hundred and sixty-two customers reviewed it, and not one of them gave it fewer than four stars. Art of Play, the Brooklyn curiosity shop that curates kinetic objects alongside close-up magic shows, calls it “one of the most captivating desk toys ever designed.”

We scored it 7.50. Our threshold is 8.0.

The Mezmoglobe is a 54-millimeter sphere of aerospace-grade aluminum with a helical groove milled across its entire surface. Spin it and the metal appears to liquefy. The helix flows outward like water, or inward like a drain, depending on direction.

It weighs 170 grams, sits on an SKF stainless steel bearing (the same Swedish manufacturer that supplies industrial machinery), and spins silently for up to two minutes. It comes in a branded zippered case with an embossed leather base. The patent is pending.

Who Made This

Kristoph Krisjans designed the Mezmoglobe in Latvia. He works with his two brothers. Before this, he created the Moondrop (a fidget toy simulating lunar gravity), the Vortecon, and Gr2 Spheres.

The Mezmoglobe was his seventh Kickstarter campaign. It raised £232,331 from 5,145 backers against a £3,000 goal. Across all campaigns, the team has delivered more than 15,000 desk toys to over 9,000 backers worldwide.

Digital Trends interviewed Krisjans at launch. He told them he had been fascinated by physics toys since childhood, particularly spinning tops with drawn spirals that create hypnotic effects.

The Trust Picture

On the brand’s own site, powered by Judge.me (a third-party review platform), there are 162 reviews at 4.92 stars. Ninety-one percent are verified through Judge.me’s invite system. The store has earned Judge.me’s Gold Verified Reviews medal. Reviews span from November 2020 to February 2025, with buyers from the United States, United Kingdom, Australia, France, Germany, the Netherlands, South Korea, and six other countries.

Art of Play carries an additional 20 reviews, all positive, some dating back seven years.

Not a single review, across either platform, falls below four stars. That is 182 reviews with zero negatives. For a product this simple (a metal ball that spins), the absence of complaints is less suspicious than it sounds. There are no moving parts to break, no electronics to fail, no sizing to get wrong. The most critical feedback we found was a four-star review noting the spinning duration could be longer, and another mentioning slight bearing noise before break-in.

The Confidence Score landed at 70 out of 100. The Trust Score derived from that: 7.0. The external validation is strong. The Gadgeteer published an editorial review in October 2023. The reviewer bought two units personally. Digital Trends covered the Kickstarter launch. The product has been stocked by Art of Play since at least 2019.

Where the Math Fell Short

The SleekNova Score combines four dimensions: WOW at 35%, GLOW at 25%, MOMENT at 25%, and TRUST at 15%. The Mezmoglobe scored GLOW 8, WOW 7, MOMENT 8, and TRUST 7.0.

The calculation: (8 x 0.25) + (7 x 0.35) + (8 x 0.25) + (7.0 x 0.15) = 7.50.

WOW, which carries the heaviest weight in our formula, measures discovery. Would a recipient say “how did you find this?” The Mezmoglobe has been the subject of seven Kickstarter campaigns, a physicsfun Instagram feature (reaching millions), coverage in Digital Trends, and years of availability through Art of Play.

For the design-aware audience SleekNova serves, this is a product many have already encountered. It is genuinely impressive. It is not a discovery. That distinction costs 0.35 points per point of WOW, and it is the reason the final score sits half a point below the threshold.

We looked for honest adjustments. Could GLOW justify a 9? The Mezmoglobe is a metallic sphere. It is beautiful when spinning, but stationary, it reads as a silver ball on a leather pad. Could MOMENT reach 9? One reviewer noted the packaging arrived in a padded envelope rather than a gift box.

We left the scores where the evidence placed them.

What Would Change

The WOW dimension is the constraint, and WOW measures something that moves in one direction. Products become more widely known over time, not less.

For this product, a higher WOW score would require evidence that SleekNova’s specific audience still finds it surprising, which becomes harder as its retail and media footprint grows. The trust infrastructure is already solid. The reviews are real. The craftsmanship is verified.

The gap is not in evidence. It is in novelty.

That is also the one thing a campaign total cannot tell you. Five thousand backers said this object is credible and will work, and said nothing about whether it would still surprise anyone; we have since written up what a funded campaign does and does not prove.

If you are looking for a kinetic desk sculpture that did clear our verification, the PlayableART Helicone is a Fibonacci-based kinetic sculpture designed by a Stanford professor. It scored 8.4.
