SLLC as platform for multiple real estate investments

I've read that Series LLC (SLLC) may be an effective platform for multiple properties.
1. Anybody has experience with SLLC?
2. If positive, any experience with Delaware SLLC, registered to operate in Florida?
Thnx

Each property is insulated from other properties liabilities and can have different ownership. \n2. Can't comment on Delaware or Florida, we just do Illinois series for Illinois properties.", "replies": [{"id": "ib5uhgq", "text": "Thank you", "replies": [], "depth": 2}], "depth": 1}]
