"I received the package and promptly installed it yesterday. I've had some of the best extrusion I've seen in probably a year. It's been frustrating. This new piece is very cleverly designed and seems to work perfectly. I'm going to recommend one to everyone I know with a 3D printer."

"I just bought and installed the purchased aluminum version for both extruders on a Wanhao duplicator 4S. Also upgrded to the Micro Swiss All Metal hot end... The system is working flawlessly. Haven't had to tear appart the head to declog filaments since the upgrade. Accuracy and thermal stability are improved as well. Thanks to DHeadrick for the design and implementation as well as support beforehand... Thanks a lot. The upgrade is well worth it!"

"I am going to completely upgrade both my machines. These upgrades rock, the ease of installation and the reliability are worth it."

"I just received your extruder modules for my Replicator 2x. I had it installed in a few minutes. This is without a doubt the best thing I’ve ever done to my printer! I no longer worry about whether or not a print will fail from extrusion issues. The quality and fit of the parts are excellent! Great product!"

"Just wanted to say thank you for the superb upgrades for my 2x. I have them installed and working perfectly, excellent quality and design. Oh, and now I can heat the build chamber to a higher temperature."

"I cannot say enough good things about the quality, fit and finish of the parts. The whole experience has really had a feeling of quality and professionalism."

"Just to chime in, this is a fantastic upgrade, easy to install and corrects a lot of issues."
G.P. (San Francisco, USA)
"In fact, this upgrade is so good I used it last year on the Ulti-Replicator demonstrated at Maker Faire and using it again this year for public demonstration on the "Ulti-Replicator 2". It looks great and performs even better."

"Pay the $88 and buy the Aluminum module. It rules! The beautifully machined compact design is easy to remove disassemble and service. Tension adjustment is a snap as well as super quick filament swaps with the "de-tensioner" feature."

"...your extruder has been the best upgrade I have had since owning this printer. So far everything I have printed has come out far exceeding my expectations. Before, I would hope that I wouldn't get an air print half way through a ten hour print."
