Meta mask is a web wallet supported by chrome & brave browser ,that is specially design to server the Ethereum community,by storing information about users Ether and ERC token.
As a blockchain game enthusiast i didn't have a second thought on trying the wallet out with the recent innovation in blockchain games were Ether and ERC token has replaced Bitcoin as a payment system in the future of the blockchain game & as a means of making deposit and payment. I see the meta mask wallet as a fun fair wallet were I store little funds just to entertain myself when playing blockchain games that accepts Ether and its token with its great compatibility with an android device .
With its simple layout interface the wallet is made less complex for new users and with the help of FAQ (frequently asked questions) they can surmount any problem they come across while using the wallet. As an open source wallet storing user's key on the users server it makes transactions snappy and faster and provide a top notch security by reducing the risk of hacker being able to penetrate the user's server.
Improvement is one thing meta mask does often as it is possible it still make amendments on its existing feature .but never the less, my users experience so far on the wallet is magnificent.
