Genuine cheap Android reviews

Hello guys,
What services/methods do you use for genuine android reviews and how affordable are them?

You can post a task at NeoBux, that would be cheap

Also looking for a source for this

There are a lot of services available
But before buying a decent amount of reviews anywhere - I would recommend you to check them first with a small amount of even a free test (the good providers always offer a free test)
You need to check if:
- the reviews wont be deleted after several days
- if the texts would be relevant to your app and not just 1 word reviews
- you should have an option to choose a custom daily speed and send your own reviews texts
- for iOS you should have an option to place reviews on different countries since each of them has its own reviews/ratings counter on App Store
