I use it on cause of Google's Android app store. Frankly no good nor bad experiences, since I've only been a buyer and haven't looked into how much of the pie Google stuffs into its big mouth. I do find putting the gatekeeper function of moving money into the hands of a player with such obvious conflict of interest as Google highly problematic, so I would never have used it outside Google's own walled gardens. (I think it's a good idea not letting banks do other kinds of business... No, Google Wallet is not a bank, but they provide services normally associated with banks and giving a little of the power banks have.)
