The worst dryer I had to use was a Hotpoint from the late 70's, early 80's. The type made by GE, the front top half of the cabinet is the whole door. Quite ugly styling if you ask me. The thermostat was wrong from the day we got it. It took more than an hour to dry a full load of towels. If not an hour and 1/2. The drum was black, with some white speckles. No drum light. it was so dark in there. I hated that dryer. The inner door was always dusty with lint. And the matching washer, the Hotpoint with the the tub ring filter. The equivalent of the GE filter flo without the filter flo. LOL. The noisiest washer we ever had. that's why I hate the filter flo washer and dryer sets. They are horrible.
Now I am so glad I have the Whirlpool machines in my house. Top Loading, contrary to popular beliefs on this site, it does not shred anything. The Dryer is the 6.5 cubic foot with lint filter on top. Greatest dryer. quiet and fast, and I use low heat setting most of the time.
That's my opinion, my friends.
