Durable, highly adherent abrasive triangles at a high price

Especially in the last two years I have restored a lot with eccentric and delta sander, off or sanded. In addition to our garden shed, garden chairs, a wooden door, wooden tiles on the balcony and wooden windows I have for example, ground to a wagon wheel. Of course I have to take a few abrasives and have tried in the meantime cheap from a hardware store, but I am ultimately changed back to Bosch and take the high price in purchasing. My findings I would like to present an overview.

ADVANTAGES
+ 10-piece set with 5 different grains
+ The original Bosch sanding triangles adhere clearly stronger at the grinding disc as "alternative products" (I call them unaware of cheap products, because there are actually good alternatives)
+ Original Bosch abrasives guarantee a good grinding performance
+ Fit perfectly on course holes and edge, so that the grinding disc is protected
+ "More", that is the fabric of the abrasive triangles is thicker, so that they can withstand significantly more when times where hangs

DISADVANTAGES
- More expensive than the alternatives! I can not explain to me why other manufacturers can offer the 5- or 6 times the amount of sandpaper for the same money and Bosch demanded so much money on it

Overall, the Bosch grinding triangles stand for quality, good abrasion and longer service life. Whether these facts justify the significantly higher price compared to alternative products, everyone must judge for yourself. I am back after a long time to the originals, since I was also partly very disappointed with the simple products eg. By a priori non-adherent pads, by quickly torn abrasive and thus defective grinding discs, which then led to follow-up costs again

I pull off a point because the here offered, expensive grinding triangles already very similar to the alternatives and is obtained as a hobby nearly the same result with alternative products. The grinding triangles offered here in red (Bosch 2609256957 DIY Schleifpapierset, 93 mm 60/80/120/180 / 240K, red) differ only in color.
