Review on High Performance 6 Inch Hook and Loop Sanding Discs: 30 Pack with Various Grits (1000, 1500, 2000, 3000, 5000, 10000 Grit) for Fine Sandpaper, Aluminum Oxide, Wet Dry Usage - Perfect for Car Polishing & Paint Finishing by Austin Cejudo

These aren't the worst third party sanding pads I've used. Although they are theoretically compared to 3M or other big name abrasive manufacturers, they appear to be great price tags. Unfortunately in the real world and in my experience 3m discs easily last 5-10 times as long and my biggest jobs require the use of grinding discs on wet surfaces and Trizact discs can be used on wet surfaces with ease and these Things fall apart instantly! The abrasive material is removed first and shortly thereafter the adhesive begins to separate, separating the remainder of the disc from the engagement material. The higher the grit, the shorter the duration, even the smallest success can only be achieved if the surface is made of bone. dry and at very low speeds. Conclusion: These grinding wheels are short-lived, use poor abrasives, do not handle water well, so not worth the money. I would suggest going with the tried and tested Trizact instead, they are definitely overpriced but last a lot longer and offer a very important peace of mind.
