PG is not a gel, sorry, and the main ingredient in the carto is not water.
If you're the one who made this, honestly, good effort, but you really need to research your facts, because people are going to be listening to you.
The one thing i agree with is concentrating on the throw-aways and such - they were reviewed a long time ago by others, but you have to dig deep to get the info, because they're considered old fashioned now, and there's a TON of them out there now.
A few notes on presentation -
You need to set up like the others do, so people can see your face. Personality goes a LONG way in video, and a disambiguous hand is not very entertaining. The way you're demonstrating the products is kind of creepy.
Show the packaging with the products, especially with mall stuff, so people can spot it.
A script or outline would do you some good, until you're more comfortable to wing it.
Be more assertive. You DON'T have to recommend everything, but just do a pro and con list, and let people make their own mind up. You can rate them, too - give them a number between 1-5, and show charts comparing price and performance and such.
Invest in a better web cam or camera, and video editing gear, and learn to do simple edits, maybe an intro bit of text, and show the brand name when testing them, and set up a "studio" with no background noise, and we don't see your desk and room clutter. All of them, Grimm, Trip, Phil, they edit and do different takes, and that extra effort shows.
Get the YouTube channel set up - the name on the account is a man, and the icon is a woman. Not a lot of credibility with that, it's a red flag for a throwaway account, a spammer, or a troll.
TLDR: good concept, execution needs work. Keep going!
