Excellent replacement ink. I've been very happy with BCH ink for several years. Previously I've used this set of six in an Epson XP-960 and now in an XP-970. The colors are bright, well saturated, and produce excellent results with any print software.

Best place for parts and accessories I ordered this print head carriage after watching a few bch videos wanted to fix and upgrade my cr encoder sensor while i was at it and i was not let down censor is original and whole assembly is new and never been used could not be happier thank you thanks Kevin!!

Great products for maintaining a dtf machine. The filters are too small for my xp600 machine All the products are good, some are too small for my needs but that's my fault. Filters are too small for my A1 dtf machine. I can still use the syringes but I really needed larger capacity to be efficient maintaining my commercial machine. Quick shipping, products are always quality and packaged very well. I've learned so much from all of the videos. Thank you!
