Has anyone here actually used a professional packing service?

I'm moving next month and the thought of packing my entire house is already stressing me out. I keep seeing ads for professional packing services where they handle everything from wrapping dishes to boxing up books.

It sounds like a dream, but I'm a little skeptical. Is it really worth the cost? What was the experience like? I'm mostly worried about strangers handling my fragile and personal items.

If you've used one, I'd love to hear your honest review. Did it save your sanity? Were there any surprises, good or bad?

For anyone curious, I found some basic info on what these services usually offer here.
