Shredmore's are that bad.
I had a TOL Kenmore in the early 1990's that my mother bought me when I moved into my trailer. It had the dual-action agitator and triple dispenser. It was the next model down from the solid state electronic machine. I used it for about 6 years, and never had anything ripped or shredded.
I washed jeans, towels, and sheets in the heavy cycle which had the fastest agitation. Dress pants, dress shirts, and every day shirts were washed in the Perm. Press cycle which had a gentler agitation. It was a great machine, in fact I wish I still had it today. I had to move out of the trailer and mom stored it for me for a couple years. I finally told her to sell it, because I didn't think I would be moving back into a house anytime soon. I just like the belt drive machines better.
My roommate works on a gambling boat as a bartender has has these crappy shirts he has to wear, and I don't know if it's my washer that is causing it or the cheap material that the shirts are made of but, he has gone through several shirts since he started working there. The seems rip and the buttons come off. I wash them in warm water, on a short or gentle wash with a low spin in my Frigidaire front loader. I think it must be the craftsmanship of the clothes because these shirts are the only clothing items that are coming apart.
