May I ask the following the questions about the GKA2 series keyboard?
1) What is the difference between GKA2-02B and GKA2-01B keyboard? Was any enhancement made? When clicking "Buy at Amazon" in GKA2-02B page on iclever.com, the product is shown as GKA2-01B in the Amazon product title.
2) I note that in the market, there is a product version GK15 with keyboard and mouse combo. May I know if the keyboard in GK15 is equivalent to GKA2-01B or GKA2-02B, or another model?
