Polystar as a brand has gained popularity in Nigeria because it is an indigenous brand, their products are cheap and we Naija people have a soft spot for cheap stuff.

And to be fair, they have some good quality products.
Be that as it may, this fridge has some selling points which include:

It uses pure copper coil for the evaporator. This is a true sign of quality and most freezer/ fridge experts believe that appliances that have copper coils instead of aluminum tend to last longer.

It’s true in a way. Although I’ve seen fridges with aluminum coils that last for several years too.

But the fact that this fridge has pure copper coils and is still more affordable than an LG fridge is a great selling point.

It cools very fast and the freezer compartment freezes fast too. Put stuff in this fridge and it would get chilled within an hour.....
