Official description:

The perfect finger spin yo-yo for everyone!

The SONiC WAVE is the ideal yo-yo for you if you:

• already know how to bind
• are up for really cool finger spins and DNA tricks
• were a fan of the iCEBERG or iCEBERG CLASSiC
• or simply enjoy YoYos with real stability and power

That's exactly what drove us during development: we wanted to bridge the gap for everyone for whom the new iCEBERG is perhaps a tad too wide and the CLASSiC too narrow - with the SONiC WAVE we are right in between. In addition, we have been able to optimize the stability of the spin with the internal stainless steel weight rings - this helps especially with horizontal tricks and when hitting the finger spin.

With the typical iYoYo features such as the material combination of PC + stainless steel, ideally designed finger spin hubs, grippy iRiNGS response pads and the string-centering PiXEL Bearing in ABEC5 quality, nothing is left to be desired. If you are curious, the supplied string is a SLACKiES (thin).

We explicitly do not recommend the SONiC WAVE for total beginners. You should already know how to bind. 
A tip for advanced players: the SONiC WAVE is also a BANGER for 3A and 5A!
