Service and support of website is quite good. Quikr is online selling website where till today I sold only 1 thing that is my furniture(Table) . I posted their a lot of things to sell but it take a lot of time to sell any product.
I you want to sell anything then you have to be patience even for so many years also. No guaranteed when you got customer for your thing.
Design is quite good. I can post a particular thing in a different section. It make easier for buyer to found particular product.
App loading time is on average and I never used it website.
At end It will may or may not be useful for you.It depend on locality where you are living or want to sell things.
