1.Save time emulating by not having to waste time firing up a computer for starters

2.The key tool fits in your pocket.

3.Key tool is a must 

4.Both xhorse
But key tool is hand–held

5.The Key tool is convenient and saves time. It’s a great addition to the VVDI2. And if you have activated 48 copy on VVDI2 you can bind your key tool and use that to copy 48 without buying additional activation.

6.vvdi key tool is mainly used for chip copy and remote generation
