seeking reliable experiences on siemens' support

Yo folks, anybody using Siemens stuff? We've been on their ecosystem for a minute and honestly it's pretty solid. Their customer service can be all over the place though, half the time you get a total pro who fixes everything in no time, other times you're stuck in never-ending ticket loops. But all in all, the reliability makes up for the headaches. Anyone else got thoughts? Curious what the vibe is.
