Just a reminder that Amazon will promote these fake stores more than real independent stores. If you can not find the store, it's 99% fake. Some of these are Trademarked, you can trace it back to China in some cases. Some are bad, some aren't, still the products won't last forever. These products are build by the cheapest material possible. You don't need a extension, you just need to google these fake stores because they won't put in the effort in making fake websites. The ones that do put in effort are poorly made, a red flag.

So to recap:

1. Don't buy from Amazon, avoid the problem

2. Look up fake store, if you found something

3. Study the website/trademark for clues
