I am from Africa and to get a Asic miner fixed if anything goes wrong will be hard that's why I plan to get the strongest and also I don't plan on doing overclocking, I want the miner to last for a very long time, thank you for the advice I will check the link out.
Be careful from the zionodes posted above they are not well-known here on the forum, there is someone who mentioned it here with the URL link to their subdomain but accessing the website is collecting data like IPs. Another thing is that their website looks like Cloud mining they design it as a marketplace but don't have a physical product.
About looking for most stronger or you mean has fewer issues then units from Canaan would the best choice according to
this.
