Noise and vibration have always been a dealbreaker for me when choosing machines, especially for clients who sit for 6-8 hour sessions. I recently tried the Vlad Blad Ultron 4 Pro and it’s easily the quietest stroke-switching machine I’ve handled. Vibration is down around 80% compared to my older models, which not only keeps the client more relaxed but helps with hand fatigue on my side too. But don’t let the quiet fool you — it’s got a M3Ultra motor with DirectPower that delivers consistent punch, even on ultra-low speeds. I’ve used it for detailed dotwork at 10 Hz and also pushed it to 130 Hz for solid packing and it didn’t flinch. The build is tough too — aerospace aluminum, carbon fiber, and titanium all around. I used to swap between two or three pens depending on the session, but with this one, it’s just easier. Everything I need in one body, no noise, no power dips, no struggle. Worth a look if you’re tired of compromise.
