I do use the app of smartprix and the good thing is you can comapre the price of any product regarding to diffrent site it will show you which online portal is selling the product in the least price which is really appreciable.
In my concern you may save your lots of time by using this app. You can comapre the rice of product.
You can compare the specification of electronic product eith other products so you can have a good idea of buying a good product.
It is relible because the price this portal showes is real .
No fake prices are showeb to attract consumers .
It runs good no pop ups are there to irritate you no so many add on app. The app and the portal both are user friendly and easily open with time no issues in that.
Where as there own delivery timing is late they took qrroun 2 or more than that too deliver
So I suggest you too only compare products specification and price.
