The Vitality by BigYoYoString was designed by Joshua Rodriquez with the help of many others in the yoyo community. The Vitality is the first non-One Drop produced yoyo to use their Side Effects technology.

The Vitality was originally designed by Joshua Rodriquez in AutoCAD when he was one day just learning how to use the program. He came up with a design that looked promising to him and decided to pursue looking into getting the yo-yo made machined.

He contacted David from One Drop, and was able to be given the luxury of using their Side Effect Axle system. After this, Josh decided that his skill was nowhere near what was needed to cut out the old hub, and or re-design the yoyo around another file, so he contacted Landon at 3yo3 yoyos, and proceeded to have his yoyo design reworked, and essentially "fixed" as to not end up with a bunch of yoyo's that vibrate for his initial prototype run.

After all this was said and done, Josh then contacted Alvin from Foxland Precision, a very small machining company, as well as a yoyo company, and had him bring to life, The Vitality.
