The TP-Link switches really seem like a good alternative to me (outside Brazil). Here the prices are not that different when I compare (in R$) Ubiquiti and TP-Link products, so I'm thinking about waiting a little longer to buy a UniFi Flex Mini switch. However, I'm also very anxious to start testing and playing with my IoT devices, as well as setting up an integrated network for my home and office. I'm tempted to buy a cheaper managed gigabit switch (around 20 dollars, including BR taxes) that I found on AliExpress.
