Fast execution of the order. All is going well so far.
Machines were as described, communication was excellent and additional support was given.
Things went good, despite unforseen shipping issues on the postal service’s part. We had a running dialogue throhought the proccess - look forward to assemble the machine and try it out!

Communication was perfect, profesional, and also Machine arrived in perfect conditions.

Thank you.

Gunter was very welcoming and helped me through it. I havent tested the machine at home yet and I will keep in touch with him as I do it.

So far I am very happy with the service.
Superior injector, waaaays better and more powerful than regular PP-injector.

Shipping went well, easy assembly and super support from Guenter who built the injector. Would recommend to anyone injecting plastic
