Toner specks appear all over the page. It worked fine on the first day of installation, but then the quality deteriorated. It's been 5 days since I've used it and the manufacturer/seller hasn't responded so it's back to Revain. The original Brother drum is around $130 and this one sells for $25 so that's a fantastic price but if it wasn't for the toner smear. question, it would be great value for money.
