Which As Seen on TV products do you swear by?

Now, we've all made fun of silly informercials (remember Shake Weights?!) and there's been some seriously useless items (no one in their right mind purchased pajama jeans), but there's also some legitimately good as seen on TV products on the market. I'm gonna say it: the Squatty Potty is one of the greatest inventions of our time.

Another as seen on TV product that I absolutely cannot live without is the contour leg pillow. Game changer for my sleep: https://www.amazon.com/Contour-Legacy-Support-Sciatica-Pressure/dp/B07MFN8FRT?ots=1&slotNum=4&imprToken=98c00091-c9e8-4db7-c7f&tag=readerwp-20.

Which as seen on TV products were worth three small payments plus shipping and handling? Act fast!
