I purchased this tv to replace my 2013 model 70" Vizio (also purchased from Sams Club) and what an upgrade. Picture quality is amazing, connectivity is flawless, and it has most of the major steaming apps available. I shopped around and looked at several tvs before making the purchase and dollar for dollar, this was by far the best deal to be found. My other Samsung tv is a 15 year old lcd that's still going strong so I have hope that this one will be with me for many years as well.
The 1 star review from the person having internet problems, that's not an issue with the tv, that's a network configuration issue.
