JARBO 1 Set Compatible Ink Cartridge Replacement for Brother LC3019 XXL Super High Yield, Compatible with Brother MFC-J6930DW, MFC-J5330DW, MFC-J6530DW, MFC-J6730DW Inkjet Printer

Excellent quality and comfort. Works awesome with plenty of adjustments and ease of use.

Works really good, better than some other of my helmets that I use everyday. Although I had to let it sit in the sun and charge for a little while before it worked properly.
