I have recommended electronics, gear, tools and materials shared along with showing where to purchase these upon.
The Amazon links are through my associates account which in turn I receive a small amount of compensation for successful orders. I’ve also noticed I also receive a small amount of compensation for additional items or alternative items that are purchased entirely just because the buyer started their shopping session with the links. I recommend checking out their affiliate program at https://affiliate-program.amazon.com so you can use between friends for that matter when doing Amazon purchases. The other references I am just sharing who I use upon, not at all receiving any compensation. The links are copy and paste in order to keep the it within SEO/Search engine requirements for better positions on the website placement.
