I been taking advantage of it to open a few lightning channels. Consumed maybe 10 TXs the past few days. Nice to get in for 10-15 sats/byte on all of them. Used mempool.space, connected to my node to watch the fees on the prior 3-4 blocks and made sure I was one sat higher than the fees being paid on them. Worked like a charm. Had one transaction get in a block within 2 minutes, for under $2 in fees, actually!
