Updated live: Not all Prime Day deals are good — we found 31+ that actually are

Prime Big Deal Days is here, offering discounts on tech, beauty products, kitchen gadgets and more during the 48-hour sale, which is exclusive to Prime members. I’ve covered Prime Day, Black Friday and Cyber Monday for five years as a reporter for NBC Select, so I know how to find deals that are actually worth buying. I combed through Amazon’s many deal pages — through thousands of discounted products —  to find the best October Prime Day deals. Each one I recommend below is highly rated, at least 20% off and at its lowest price in at least three months. I’ll frequently update this list throughout Prime Big Deal Days.

It fits inside drains that are 1.5 to 1.75 inches wide and doesn’t disrupt water flow.
