The quality is not the best , but the variety is good , perfect to normal projets

Purchased these for "coping" baseboard inside corners. Novice DIYer. Saw a video using an angle grinder instead of a coping saw to do this. Was worried about my ability to control the angle grinder sufficiently to get decent results. No issue at all. Much easier to control than I expected. and the learning curve short. The result was better and quicker than what the coping saw could do. I've used a single 40 grit disk to cope inside corners on about 300' total baseboards. Better longevity than I was expecting.

The media could not be loaded. This months project, we transplant a Vulcan watercooled v twin vn800cc engine into a custom kart.A few years back, I saw a flapper wheel for the 1st time at my welding supply shop. So, I bought one... they were 14 bucks each! Like the salesman said I would, I loved it. The design performs better than you would expect. All the pads I've used cut well without gouging your metals, this saves time when finish work is being completed. I was concerned about life expectancy of this unit but it perfoms close to the 14 and 15 dollar wheels I've used. One thing I'd like to see is the threaded nut built to pads center for faster change out.Flapper wheels are not going to replace all grinding wheels. You never want to grind out a slot on metal where the pad kind bind and it will not cut... I have 6 or 7 cheap Harbor Freight 4.5 inch grinders setup on my cart since I'm not a commercial user. Financial it makes more since than having 150 dollar grinders the 20$$ grinders work just as well . I have a normal thick grinding wheel,cut off wheel, sand disc,wire wheel, and a few flapper setups with different cutting grits. Besides fighting with cords its seemless and fast between changing my disk needs while building. You can't really go wrong with this product.. the best most over looked positive about a flapper wheel is very little grinder dust comes off them while using...Cheers keep building, fixing,designing, and please take time to teach a kid your skills.

I used to buy sanding pads one or two at a time at the hardware store when they were like four or five dollars a piece! Here you get 20 piece's for like $2 a piece!... they're very good and well worth the money buy these and get your money's worth.Thanks Amazon for this great deal!

Initially got this to remove Deck It product off the deck of a home recently purchased. The deck was all scaly and bubbly, product wasn't properly applied I'm guessing. Got the grinder out and added a pad and like magic I was down to bare wood. Unfortunately my knees are not designed to crawl around and do a 12x16 deck and after thinking about restaining, etc we put in a trex deck. But wait, the deck had a skirt around the base that also need sanding so off the pieces came. One by one I "quickly" was able to get to bare wood with these pads. You have to be careful as you can get uneven swirl marks which would have to be smoothed out with a hand sander,etc. I got the hang of it and was able to keep swirl marks to a minimum. The pads are very durable if you don't hit a nail. If you just want to quickly get to a clean base to start over painting, etc. these are your go to pads. I wasn't to concerned with swirl marks but if you are a belt sander might be better. Belts may be much more costly also the grinder is lighter and easier to handle, just my thoughts.

First off I like the price point. I’ve only used the 60 and 80 grit discs so far. I use them in both angle grinders ,battery and corded.Work as intended for light to heavy sanding mostly on wood. I also use on cleaning up tube stock before welding.Yes, totally a consumable item but for the price and what I use them for I give them 5 stars.Haven’t experienced any manufacturing flaws as of yet. I received the proper amount and the various variety of grits as advertised.If you’re looking for middle of the road? This could possibly work for you.

I buy these often. Can beat the price. Way cheaper then buying from AirGas

Compared to the local hardware store, this multipack is an amazing deal. The one made by Diablo is about twice the thickness of the ones made by LotFancy and in my experience, the Diablo flapper wheel lasts more than twice as long. However, at $9.47 at my local Home Depot for just 1 wheel, the 20 piece set of flapper discs can't be beat.NOTE:LotFancy is made in ChinaDiablo is made in TurkeyFor US-made, look up Sparky Abrasives (better quality than LotFancy, much better price than Diablo)
