Hands down, this is the most realistic turbo keychain ever produced.
A complete redesign for 2017 allows customization with many improvements over the GE Family, most of which inherited from priorversions. Upgraded features contain dual twin shield ball bearings, ultra realistic SHF (Super-Hi-Flo) impeller/turbine; semi-clockable housings, center cartridges, and other parts interchangeable within the TK10 family. Both impeller and turbine are interconnected to spin in unison and sounds just like a real turbo when spooling quickly.
Every unit is hand assembled in USA and ships fully tested. Production is initially limited to 5 per day which makes them very exclusive.
