Very disappointed, worse than dual core

We have had a dual core stick from Rikomagic. The logo was somewhat different. But since I did not think anything.
Now we have this ordered here. In idealo there was the stick a lot cheaper.
Rikomagic = good company I knew.
BUT:
1. The resolution can still only 720p
2. We have permanent problems with the Wi-Fi connection

THEN:
In desperation, we looked on the internet to the manufacturer. Rikomagic found, unfortunately angeschriben only in English and taken to task. The answer was very blatant.
Rikomagic is a manufacturer from China and Hong Kong. In Germany, however, another company had registered the name as a trade mark and would include selling inferior products.
I can not confirm because I've just ordered a product from the "German Rikomagic" I. But this is really bad and overpriced.
Maybe I also got a Monday product. Can be.

Long story short:
Stick was sent back. Dealers wanted to pull money as already used. After threats of a lawyer but gabs full money.
We re-use of dual-core Rikomagic (RKM stands on it).

PS: Will such products only from Amazon, because you get but helped here as a regular customer complaints. That needs to be said sometimes.
