Hi, can anyone give me advice about kuongshun arduino uno r3. Apparently they are giving for free with some prize and need to pay shipping 10$ but is it actually cost effective or can i find for same price something similar.

can you wait 20-60 days? I think you would find the same quality at Aliexpress for a lot cheaper.

I am under the impression that almost everything you buy on Aliexpress has not paid the licensing fee.

Since most of the world's electronic manufacturing is done in China (China has very lax environmental laws) there is a lot of competition which means that the quality must be good to minimize returns. This quality tends to spill over into the cheapo market.

So the quality is about equal, but you're stealing from the designers and polluting the earth.

I have gotten the kind of jumpers that are in the Frenove kit and they do not make good contact. I don't know where to get good jumper wires. The Larvin kit looks like a better value, but "better" is a relative term.
