TerrificDon’t waste your time or money. These are absolute junk. If you’re lucky you’ll get maybe 30 seconds of use before the velcro separates from the sandpaper…Amazon won’t let me leave 0 starsThese are quality papers with good adhesion, and the grit assortment is perfectly fitted for my needs.The only reason I didn't give these a full 5-stars is due to the damage on a few of the top pieces in each bundle.The edges were damaged in shipping, but they were still usable.Some of the venting punch-out dots weren't completely removed as well, so that was additional work for me, but it was really only a minor inconvenience for a good value like this.They fit my 3-1/2" sanding heads perfectly, and the papers took quite a bit of punishment before they 'loaded up' and needed swapping out.Overall, this is a great value, and I'm pleased with the assortment.If I hadn't had to question the frayed edges on the few that saw some minor shipping damage,these would have been 5-star items.They're doing a great job on sanding my decking, and they adhere VERY well with no slippage and minimal edge fraying.I always seem to be missing these when I need them, so I got a nice set here of assorted grits.You can never have enough of these.I wish these in general would last longer, but this is a good price to a bunch.The Airic sandpaper was ordered for use with my oscillating sander.This is a really good assortment of varying grits of sandpaper for use with oscillating sanders. The triangle abrasive paper is made to fit sanders with 6 holes and is a 3.5 inch pads. These fit my sander perfectly. The sandpaper fits on those sanders with hook & loop (velcro) fasteners. These fit and removed easily after use. The mixed grit order (60, 80,120, 180, and 240) worked well with wood when tested, and based upon experience the 180 & 240 grit should smooth plaster finishes nicely.The quality of the sand paper was just as good or better than most of the other brands I have used in the past.BOTTOM LINE: I've purchased sandpaper in the past for my oscillating sander at higher prices than the current price point for this product. The quality of this sandpaper is just as good or better than that I've purchased in the larger hardware stores in the area. It tested well on wood in all grits, and I would definitely order this sandpaper again.Good quality sand paper. Was a bit small for my sander so double check the size you need. That's on me though. Nothing wrong with the paper. Seems to be made of good quality material.It is my own fault, but I assumed these were one size fits all. I know now that I was wrong. The pad on my sander is about twice the size of these pads. I will try to use them for hand sanding. They appear to be okay other than that.These work great! They fit the sander my Dad has perfectly and they sand my wood projects beautifully. So smooth! Perfect grit and product to leave my shelves feeling like velvet and never having to worry about getting a splinter.
