I bought these to compare with some Target ones I already have. The Patvingot ones are slightly thinner and the color is a bit more yellowish than the photos showed online. They work fine for holding towels in the bathroom, but the "paper rope" feels like it might unravel if it gets too wet. They're fine for the price but don't expect luxury.

This is a high-quality aluminum oxide. While the price is a bit steeper than some bulk options, the consistency of the grit is superior. I noticed fewer scratches and a much faster polish phase compared to the standard 8000 grit I was using before. Definitely worth the investment for competition-level stones.

This FH Group liner is way better than the generic one I bought at Walmart last year. It actually feels like it belongs in the car. Great price point for what you get.

I’m actually surprised by the quality of the Hibbent aerator. It’s solid brass so it feels heavy and durable, not like those cheap silver-painted plastic ones. The 360 swivel is a game changer for cleaning out the corners of my deep sink, plus the spray mode is powerful enough to knock food off plates without being too splashy. Only downside was I had to use my own plumbers tape because the stuff in the box was kinda thin.
