Yeah, here in the South-American markets it is actually difficult to get much else than TP-Link hardware. Importing networking gear is terribly expensive here. Amazon/Ebay/NewEgg do not ship to here, so you must pay for a service that receives your goods in the US and then sends it to here. That service bases their tariff on size weight and what they think the package is worth.
Then it arrives at customs and they add a tax of what they think the package is worth as well. And no, the value on your receipt has barely any influence on their opinion.
My friend bought a sound bar for under the TV on Amazon. A Yamaha unit, for 130 USD. When it finally arrived an extra 100 USD was slapped on. That is the cold hard reality here.
People have barely any other option than purchase the TP-Link hardware that is on offer here. Sure, from any other standpoint your advice is valid, But here in South America it is just as useful as Santa Claus, unfortunately.
