Buggier than dog poop. Paid a request from my dog-walker twice, and then Customer Support said that because the money has already landed in her account, there's nothing they can do and it's up to me to get her to send the money back. Corporate responded to complaint by claiming she sent me two (identical) requests and that I paid both, only 2 seconds apart (yeah, like that's credible). I found over a dozen other people complaining about this just on Twitter; no one ever got their money back from Venmo. Venmo also sent a payment meant for a friend, to both my friend AND my gardener, both with the same comment, same timestamp. My dog-walker and gardener both sent me the extra money back, but this app cannot be trusted to send money if you can't trust the recipient to return any overpayment. I have filed complaints with the FTC and state Dept of Financial Protection.
