Honestly I’ve never had a problem with robosats. It’s been really smooth and no issues. I typically pay using Interac or shakepay (shakepay is the fastest way to pay). I typically set my premium at 2.5% or 3% and usually someone picks it up.

It works exactly as designed. They have a great support telegram if you have any questions anytime

Actually there have been a couple times when a seller hasn’t followed through.. but when this happens you get your full deposit back AND you get a portion of the sellers deposit as payment for wasting your time
