You can easily switch between and customize the R4's dynamic Give settings by following these steps:
Switching Modes: Double-click the Power button to cycle through M1, M2, and M3 modes.
M1 (100% Hardness): Delivers a firm, direct hit, ideal for crisp linework and working on thicker skin.
M2 (80% Softness): Provides a softer, more cushioned hit, suitable for smooth shading and a gentler working feel.
M3 (Customizable): Allows you to adjust the Give level from 10% to 100% to match your personal tattooing style.
Customizing M3 Mode:
Switch to M3 mode.
Press and hold the Power and "+" buttons simultaneously for 3 seconds.
When the indicator starts flashing, use the "+" or "−" buttons to adjust the Give level from 10% (Softest) to 100% (Hardest).
How do I choose the right stroke length for my work?

3.5mm (Medium Stroke): A versatile all-rounder for delicate fine lines, intricate details, realistic gray wash shading, and smooth tonal transitions.
4.2mm (Long Stroke): Offers a firmer, more impactful hit, making it suitable for crisp, bold linework, traditional shading, and efficient color packing.

After a few sessions, I can finally share my first impressions.
At first, it felt a bit heavier than my previous machine, so it took some time to get used to it. But after a couple of tattoos, it already felt completely natural.
What impressed me the most is how stable it is. No matter the angle I’m working at, it stays smooth and consistent, giving me much better control. I’m also a huge fan of the M3 mode—it just feels perfect for the way I work.
I’ve also noticed something unexpected: this machine gives me more inspiration and confidence while tattooing. When your equipment works with you instead of making you think about it, you can focus entirely on creating. And that’s exactly how this machine makes me feel.
Used Jconly Pen since it came out. The new one R4 It’s incredible lightweight and feel very natural to hold for me.Once reading the basic instructions, the use is quite intuitive:) I love it . Thanks Jconly for this new product.
Love this machine ! Used all types of brand name machines but this one is perfect. Balance is there and performs very well with everything I need it for. Much appreciated ☺️
Really great machine — maybe one of the best I’ve used so far.
I used to work with two different machines, each for a specific purpose, but this one managed to replace both — whether it’s lining, packing, shading, whip or pepper shading.
I think it does an incredible job. A real favorite.
I’m attaching a photo of my first test with it.

Ich nutze seit einigen Monaten einen PEN mit 4,2mm Hub von Jconly für meine Dotwork Schattierungen und bin sehr zufrieden mit dem Ergebnis. Nachdem ich Probleme mit der Maschine , sowie dem Adapter hatte , haben die Mitarbeiter sofort reagiert und mir umgehend einen Ersatz zugesendet. Der Kundenservice ist wirklich 10/10 und komplett ohne Probleme. Sollte mal etwas nicht funktionieren, werdet ihr schnell und unkompliziert betreut ! Empfehle Jconly defintiv weiter.
The delivery and the communication with Jconly were very uncomplicated and friendly! I really like the Tattoo machine , it works very well and has a great look and quality. I would reccomend Jconly. If you have any questions you can always text them on Instagram.
