I'm over 4k and I don't know what I'd do without it. I'm just about always in a swap and I go for 19 days each swap. Regular collection amount would probably be about $40 million before bills but with the swap, it's about $60 million after bills. I'm sure those figures are way off what they actually are, but you can't deny that saving 50% on infra bills each day won't save you money.
