When I was a kid there were some things I’d see and wanted, only to get them and be seriously disappointed. I learned quickly that ads are fluff.
Nowadays, I actively stay away from things I’ve seen advertised. The way I see it is if a company has to pay tons of money to get their product seen, it can’t be all that good to start with. Genuinely good products don’t need to try and convince you they’re worth it.
