    Excellent service and timely shipping – super!! This is a typical j-head, so a very high quality machined product, using the latest design.

    It does not feature the light weight aluminum head, but the tried and true bronze one. It’s also the 1.75mm machined head, so it’s not possible to swap this head from 1.75 to 3mm as it is with some of the heads.

    I’ve not extruded any filament with the new head yet, but have no doubt it will be as good as the other one I use!

    Great product, fantastic price and VERY FAST shipping!

    These 1.75mm J-Head hotends are very difficult to source in the UK/EU and Reprapshack.co.uk solves that problem! Im using this hotend on my Rostock 3D printer and it’s working great.

    Highly recommended!
