I think it will be good, however the toner that came with the laser printer, I am still using.
I let them know what happened and they contacted me and offered to ship a replacement toner at no charge -- that is what I call great customer service.
I had to buy a Brother cartridge in the interim so we could print, but will continue to use Renewable Toner for all of my replacement cartridge needs going forward - THANK YOU ROBERT for resolving this issue.
Renewable toner cartridge works great and is very economical.
It works immediately without problems.
The toner cartridge in my TN-660 box was not a TN-660.
It was labeled as a 660, but looks more like the TN-750 and it did not fit the drum.
I am not sure the ink cartridge was responsible, but my print quality deteriorated to the point that prints were unreadable.
I tried changing to a new ink cartridge since I had ordered more than one and got the same result.
I tried changing the print quality on my computer and nothing worked.
