Oppo phones are higher in cost according to the specs they are providing in their phones. Here is the overview of the specs:
Display : IPS lcd display with 16m colors but with very low ppi( say 218) , which is a major CON.
Processor : It features a QUAD CORE processor which is too low at this cost. Even the cheapest android phones are also featuring quad core processor.
Ram : 1GB ram is enough for normal daily usage but for this price I don't think its a good value for money.
Rom : 8GB internal memory is very less, out of 8GB you will only get about 4GB( max) usable memory.
Camera : 8MP rear camera and 2MP front camera which is also a major CON as many phones in this price range are featuring 13 MP rear camera and 5MP front camera
Well, I don't think it is a good buy or good value for money.
