Will guarantee at least 33 minutes for this spinner - but should be able to do much better than that.
There is a youtube video with the spinner (aluminum model) showing the 36+ minute spin time on one finger youtu.be/JY5F6TX-rXI
Here is also a YouTube video from a satisfied customer showing a blower spin with a spin time of 1h10+ minutes - https://youtu.be/_RbtAWR3U9Y. Note that the vertical spin highlights the need for radial balancing. The newer model is now smooth, and does not have that roll over effect as it is spinning. At high RPMs (with an air compressor), it does not wobble, and will stay in place over even a low friction surface. (aluminum model)
Youtube video of the alumiinum model, showing an approximately 3000 RPM air compressor spin, and the sound that is generated from the spin. Not shown in the video, but that unit got 59m44s of spin time with that air compressor method https://youtu.be/kTsTzS5Hjx4
Titanium model has been tested up to 4000-4500 rpm in a similar fashion with no wobble.
To maximize initial spin velocity, place the spinner at edge of table as in the picture, spin with a few rapid glancing thrusts, and then slowly position it back over the table itself.
Certificate with actual hand spin time of unit provided.
Can add custom laser etch/marking, similar to company logo, on the center hub, or outer ring. In addition can make custom laser design on the face if required. These can be individualized as per user choice, and would all be subject to an extra charge.
This is a one of a kind fidget spinner design, and is unlike anything else offered for sale anywhere.
