Rustam Tashbaev –
I saw 2 five-star ratings with no details and decided that it’s good enough.Out of 12 rollers, two lasted for couple of hours and stop working properly, creating loud noise. Now I have to remove intake and redo everything. Lot of wasted time and money. I will replace them all because of uncertainty in longevity.Buy such a crucial parts from reputable online stores. Pay more to save more. Amazon is the place for cheap Chinese knockouts.
