I have no complaints, but it would be nice if there were some competition for the usual reasons, such as that we're not all screwed if localbitcoins shuts down.
I did Mycelium localtrader for awhile, and did 2 trades over it, but the amount of spam is overwhelming. I finally stopped using it after the 3rd time my phone started beeping in the middle of the night with an obvious scammer asking me if I took paypal for payment. I think it's a great idea, but it needs a lot more work before it is usable.
