I have a Samsung fridge freezer 4 years old, Samsung 55" 3D TV 2.5 years old, Samsung 32" LED TV 2 years old, Samsung 32" LED TV 1 year old, Samsung 3D blu ray player 2 years old, a Samsung laptop 18 months old and a Samsung Galaxy S 3. I've owned quite a few Samsung phones over the years, D500, D600, D900, E900, i8910 Omnia HD, Galaxy S, Galaxy S II and Galaxy Nexus and I think I've even owned a Samsung camera in the past which I sold. My mother has a Samsung LCD 32" TV which is 3 years old and my brother has a Samsung LCD 32" TV that is probably 6 years old. I've also had various Samsung internal and external hard drives over the years too.
The freezer section of my fridge freezer did fail within the first year of ownership but Samsung were quick to send an engineer out to replace a part and it has been fine since. The only other problem i've had is the dog chewing through the laptop charging lead which meant I had to buy a new charger but that wasn't Samsung's fault. Statistically speaking from my own personal experience and YMMV but Samsung has been very reliable for me and I can safely say my next TV will be a Samsung and my next phone will more than likely be a Samsung Galaxy S 4 unless another Android phone comes out that is better.
