This product has been superseded by TK10-R Turbo Keychain.
The newest GE series with many improvements over the GE-S1, some of which inherited from the “Race” version. Upgraded features contain dual twin shield ball bearings, a newly designed metal HF (Hi-Flo) impeller, and lighter weight metal turbine. Both impeller and turbine are interconnected to spin in unison and sounds just like a real turbo when spooling quickly. This is the most realistic turbo keychain, in addition includes a unique serial number with Spec Card for authenticity and 6 month warranty.
If you already own a GE-S1, sit tight. We will have upgrade and rebuild kits out shortly, along with some attachable downpipes for those RC folks:)
