Has anyone switched from in-house IT to outsourcing? Was it worth it?

I’m considering moving away from handling IT in-house for our small team. Between security issues, backups, and constant unexpected tech problems, it’s starting to take up more time than it should.
For those of you who’ve already made the switch to outsourced IT, how did it go? Did it make things easier,, or were there downsides you didn’t anticipate at first?
Any lessons learned, red flags to watch for, or things you’d do differently would be really helpful. Also open to IT company recommendations, thnks!
