This pack of sandpaper is what you expect to get for the price. There is a good selection of different grit paper so you have a lot to work with. The paper is a good size both for hand sanding and if you have an electric sander.For my uses, the paper stood up quite well and delivered very good results. The paper stood up for general purpose sanding, and I was able to use it for finishing on a shower stall repair. I did notice the paper is quite thin so I can understand where other reviewers--who probably are using it in a much more professional or heavy-usage situation--may have come into issues with the overall durability.However, for the price, if you are looking for a good selection in a single order, you really can't go too wrong with this selection. It is value-priced for general usage and for that it does a great job.
