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!

Huge money and time saver!! I've been refilling my cartridges for a long time, but with my daughter becoming a teacher, printing has grown exponentially. After lots of research and pondering options, I decided to go with the Spongeless kit. I watched the YouTube videos several times before doing the conversion. It's not an easy process and requires patience, but it was the best decision ever! After the conversion, we were able to print about 300 pages without any issues, and the refilling process was super easy. Highly recommended if you have the patience and skills.
