"We worked with this Adreno technologies India Pvt ltd and paid them tens of thousands of dollars. Suddenly in November 2015 they stopped
keeping their promises on development. We continued to pay for services that were not being delivered, so we eventually cut them off. Our project is now a full year behind.
Note that they request you give them 5 star rating on Upwork/Elance feedback, so don’t trust the reviews there.
We have a site setup that will detail our issues with Adreno technolgies in more detail at http:adrenotechnologies-sucks.blogspot.in
If you have similar issues, feel free to contact us.
