I use it as much as I can, but the opportunities are limited in the US. I think Phoenix has the best non custodial UX. I stopped using them and closed my channel when they pulled out. I'd go back to that if I wasn't getting my own node up and running soon.

Wallet of Satoshi is the best pure lightning custodial experience, but they pulled out of the US so I stopped using them, though I still have the app on my phone and it works.

Currently I use Strike to pay lightning invoices using my cash balance so there's no taxable event. Not that I would report small transactions anyway, IRS can go fuck itself. They have the best mixed use app between buying Bitcoin, being able to pay lightning invoices, free withdrawals on chain, etc.

Once my node is up I'll start experimenting with Zeus and other options.

In the last month I've bought a leather wallet, a Start9 server, and soap with Bitcoin. The first two were on chain though since they were larger expenses.
