When a seller takes you up on your buy offer it's great. The problem I have with it is simply this often takes weeks.
I also don't like how only sellers can see the order book, not buyers.
And compared to Robosats, currencies and payment methods are limited and there's trading limits (about $1k USD per week so not bad tbf) and it's on-chain only. And their on-chain wallet still doesn't support taproot but at least it's non-custodial.
I do like that it has a reputation system yet is still anon.
It's worth checking out LNP2P on Telegram too. Just used it after having no luck on Robosats or Peach. Took me ~25 mins to find a seller, accept, pay, get sats direct to my non-custodial wallet.
