These seem like a clever ploy by Big Detergent to force you to spend more on rebranded soap.
Well, as it turns out they actually really work out well. Almost everyone uses a little too much detergent in their wash, but these little pods actually do the trick.
This pet comb really works: Furminator brush, a metal comb with tapered grooves that removes undercoat and reduces shedding. It's not a surprise it works, but how well it works. The ad photo with the husky surrounded by a giant pile of fur is exactly what happens.
Another endorsement: Bought a furminator yesterday and felt like a dumbass for spending $45 on a damn cat brush. Then I had a pile of fur twice the size of my cat.
RainX is the stuff you spread apply to your windshield that repels rain, meaning that you don't actually have to use your windshield wipers.
Here's one Redditor's endorsement: First, it will last a lot longer than a few days if you follow the directions to a tee. If it's at all cool air temps when you apply it, turn on your defroster for a while to heat up the window. Helps a lot. When you get up to speeds that make the rain "skitter" off the windshield, stop using the wipers; this speed will vary depending on the angle of your window. [...]
