BCH offers amazing quality products at very reasonable prices. I ordered the 4 ink 30ml kit and a larger black to refill my #62 HP cartridges. The videos are great and show how to easily refresh these wasteful cartridges and save a bunch of $. Thanks to Kevin and the team at BCH!

4-Color Dye Ink Refill for All Printers - INK ONLY BULK PACK
It was just what we needed. Thanks to your YouTube instruction I was able to order the part and fix my 83 yr old sister's printer. I am an 80 yr old female and was thrilled that this part fixed her printer and saved her some money since she did not have to buy a new printer. I have never before tried to fix something like this. Needless to say, I was surprised it work so well.

BCH Paper Feed Gear (PFG) for HP OfficeJet Pro 69xx Series - Fix 6958, 6968, 6970, 6975, 6978... "The print carriage cannot move"
After receiving the Grade A L1800 mainboard back from verification from BCH Tech and it still did not work on either of my computers (Win10 & Win11) as the same error was showing, I finally found a solution. I had to reinstall Windows (new install overtop of existing to keep all files and apps, but fixes any corrupted files) on both computers and not it is working properly. I apologize for the original negative review but rest assured it is not Kevin's fault. Thanks for you understanding and sorry for the original review.
