Alex Hattori's Boost Squared prototype version, released April 18, 2020.

Read more about the Boost Squared design on the April 2, 2020 blog at www.alex-hattori.com.


From the www.alex-hattori.com website:
"Boost Squared - PreProduction

The Boost Squared is a high performance, aluminum yo-yo, designed to perform as well as a square (squircle) yo-yo possibly can. It’s about as floaty as an SUV and as organic as an Iphone XS Max. It features a round catch zone and cup so grinds and fingerspins are easy to perform. For more information on the design process, check out this blog post! There are many noteworthy features for this yo-yo so read the disclaimer below BEFORE purchasing.

Disclaimer: This is a unique product and is not to be confused with a typical professional yo-yo. It can actually be quite dangerous if not used with care. The buyer is liable for any damage caused to themselves, others, or property by the Boost Squared. Alex and anyone affiliated with the Boost Squared design is not responsible for any damage cause by this silly creation. Read the whole description carefully before purchasing. If you want a competitive yo-yo, you can still find my design with YoYoFactory.

1) When the yo-yo is spinning, it stores a significant amount of energy and can cause pain or injury if the yo-yo engages with something too fast.

2) Change strings often to avoid the danger of snapping a string. These units have not shown signs of any additional string wear than a typical yo-yo, but extra caution must be taken when the yo-yo is square.

3) This yo-yo had to be manufactured using different methods than typical yo-yos. It is much more time consuming and expensive to make this design over a round yoyo and Alex didn’t want to reflect that in the price. As a result there is occasionally some vibe. Every Boost Squared is hand tested and assembled by Alex and is entirely playable. Do not purchase if you care about vibe on a square yoyo.

4) These are pre-production units. There are still machining marks and the aluminum is raw. Do not purchase if you want a pristine tumbled/blasted anodized yo-yo. Those may come further down the line but there is no guarantee.

5) Due to the nature of the square shape, it is sometimes difficult to get the two halves lined up. All Boost Squared are shipped clocked correctly but once a user unscrews it, Alex cannot guarantee the user can clock the halves back perfectly. This will not affect play. Do not purchase if you will have a problem with this. That being said, Alex is happy to help assist you in re-aligning the halves.

6) It’s a square yo-yo. Don’t take this too seriously. It’s meant to be fun and silly."
