I bought 2 packs of trolleys, the first one started to squeak/noise a lot after a few pages. They traded for a second carriage, which worked fine for about a month, printing about 200 pages on it. Started creaking a week ago. Replaced with the replacement of the first and it also squeaks. Maybe about 350-400 came out from all 3 sides before it started squeaking. This wouldn't be a problem if I had the printer in another room, but it's not possible. Maybe I was just unlucky, but I will not buy this particular brand again.
