this has been a great let down this has been a great let down. This is my second time trying to get cartridges that fit and i am out of time with two purchases, one return, no refund in account and asked to jump through hoops and present a Cinamax Profuction to show cartridges received do not fit flush in the Brother Printer MFCL8900CDW Series cartridges.

Great company I actually couldn't use the toner I received because it had a chip and I had trouble doing the transfer. (I Never knew they had chips) BUT the company was very responsive every time, they did things quickly, were professional, and I would definitely use them again!

best toner cartridge supplier I have spent a small fortune on non-HP cartridges that did not end up working at all on my HP printer. But YB toners worked well, as soon as I installed them. In addition, the company's customer service was great. At first, I thought I had a problem, and their customer service person responded immediately and even followed up when they did not hear back from me. If I end up having problems after I am using the cartridges a while, I will revise my review. But what a pleasure to have this printer up and running again, at 37% of the cost of what I would have paid for HP cartridges.

Update to 5 stars I initially gave a two star review but definitely want to update to five. Without writing a long story, customer service does as they say! They guarantee and replace a “defective” product. I thought they were not responding to my issue but I believe I was too quick to criticize. Thank you YB Toner. You are now my go to!

Speedy shipping Ybtoner offered me the exact product I needed at an affordable price. There was no need for me to try and remove/replace chips like other brands found at the large online store I’d normally buy from. I live in the middle of nowhere and received my package quickly. I will definitely be buying from them again.
