Super, but only when grinding wheels are used for more at a time

I ordered a couple of weeks before the grinding wheels with the "Makita sander BO5041K". The Makita was right on the next day there, but the wheels have arrived only two days later, because it is supposed to come to bottlenecks. The grinding wheels are were well packaged for shipment.

The grinding wheels themselves can be said that you do a very good and high-quality impression for your money. I have several different grinding applications with different discs behind me and was very happy with the result.

I have read several reviews that the grinding wheels change several times no longer hold. This I can only confirm. But a fair way also has to be said that is very pointed in the instructions that disconnect with multiple and attach a grinding wheel, the bond strength is no longer given. So it is unfortunately given that the slices hold ungefair only after about 3 separations and attachments to the grinder firmly. After that they are no longer usable.

Therefore my conclusion:

If you for some reason one always needs a different grit in his work and thus the discs must change regularly, I would buy these discs under any circumstances. But if someone can long grind with a slice and do not continue to rely on a change discs, I can recommend this product both in quality as well as the price-performance ratio just continues.
