The first two packs of these were failing within ten minutes of use, I just stumbled upon the 3rd package of these, along with the receipt from the shipper which I am going to leave anonymous at this time.  I tried one at work today and kept the second one in the original packaging.  It is marked as "original Fein", "made in Switzerland", etc...  I can't find the email link on the Fein website for customer service or complaints, so here it is.  They have finally cheapened these things to a point where I will never buy them again and I would imagine their sandpaper is going to suffer the same fate.  I bought my multimaster in the late 90's and it was used when I got it.  I have praised the folks at Fein for the past 15 years and I am a professional who gets to use a lot of different tools from major manufacturers.  I can no longer endorse something that has gone the way of total junk.  Either someone in another country is bootlegging these accessories or they have changed the adhesive they use to assemble the pad to the backing plate.  Either way, it's a waste of money and worse yet, time.  As a contractor, I don't mind paying for something that will perform well and last.  Kind of like a mechanic paying for a Snap-on tool.  You can't have something break in the middle of your work day, even if it does have a warranty.  Who wants to stop everything to run to the store?  Since the global patent expired on this oscillating tool and everybody and there brother jumped on the manufacturing bandwagon, the cost of accessories has come way down.  I no longer HAD to buy genuine Fein, but continued to do so because they WERE the best.  Here's a message to the bean counters in Switzerland.  When you cheapen your product to increase a profit margin a few percent, let's hope that you can survive by selling to homeowners (who don't know they are getting ripped off).  Us professionals who built you business by buying (400 dollar) tools and accessories, would like to thank you for turning your backs on us, the ones who supported you all these years.  Do I expect too much?  Maybe, but I was born and raised in Pittsburgh, a blue collar, hardworking town where tools are passed from one generation to the next  If you think you have built a tool that will last, just send it to a major city in the rust belt and we'll let you know how it holds up (in a real world work environment).
