The "Life and Tech WiFi Ultra Boost" Suspicious Websites

I have been getting hundreds of spam emails from a so-called Life & Tech that sells claims to sell WiFi Ultra Boosts device with wifi speeds up to 300mbps. After doing a Google search, I discovered that there are approximately 20 suspicious websites with domain names ending with ".bid", ".icu" and ".pro," all claiming to sell the same product. And, what makes the websites even more suspicious, is that they all have the same templates or the same design and they were called Daily Living Tech before they were renamed to Life & Tech.
