I used it quite a bit when I was in China for things other than messaging. Have to say it was a great experience, it works with literally EVERYTHING. You walk on the street - bam the bagger is using wechat QR code to ask for donation. A large number of normal people I encountered don't even use their wallets anymore - menu on wechat, mobile payment on wechat, taxi on wechat, utility on wechat. It's something that after using it, you know there's no way back.
