FingerLock 8K [BETA]

Built from carbon-fiber reinforced nylon, the FingerLock 8K delivers a pro-grade platform that isolates finger control and trains tension management. If you’ve ever felt sluggish or inconsistent on small corrections, this is the tool to sharpen your finger engagement and bring consistency to your aim.

Now, with HARD-MODE, you can swap to flexible TPU buttons that compress when over-squeezed — giving you instant, in-hand feedback so you can build a calm and consistent grip under pressure.

Fix 'Nervous Aim'

Most players don’t even notice the tension in their aim until it ruins a clutch. FingerLock can be toggled to give you real-time feedback when you over-grip, turning jittery aim into smooth control through practice.

CLOSED BETA REVIEWS

"I was expecting trade offs at this price but I'm very pleasantly surprised. Build quality feels solid with no creaking or pre/post-travel. It's crazy how far 3D printed mice have come."

- David F. / Mouse Enthusiast

"I've been hard stuck VT gold for months before full committing to the FingerLock aim training routine. I'm already pushing diamond within 3 weeks now."

- Alpy261 / R6 Diamond

"First time I’ve been able to palm grip without cramping my pinky. A real game changer for my larger hands."

- atomc / CS2 20K

"Took about a week before my aim felt normal again, don't recommend playing ranked during this time. I've used the prototype in game for a month now and my headshot % has more than doubled. Totally worth the experiment."

FAQ

Q: How do these mice help improve aim?

A: Years of playing with the same grip and aim style can create gaps in your mechanics. My training mice are built to bring those weaknesses to the surface so you can fix them efficiently. Some models force you to engage new muscle groups by isolating how you grip and move the mouse, while others focus on tension control, giving instant feedback when you over-grip.

To make the most of it, every package includes a 30-day aim training plan that focuses on the specific strengths each mouse is designed to highlight — so you’re not just using new hardware, you’re following my proven path to solo-queue leaderboards.

Q: Why is there a [BETA] tag on these products?

A: Because it’s fresh out of the lab! This is my prototype run, so while it’s already functional, I'm still collecting feedback to make it better. As a thank-you for being an early adopter, you get 20% off store-wide.

Q: Who are you?

A: I’m a Manufacturing Engineer working at a startup that builds implantable radioactive brain-cancer treatment devices. I used to work at the Starbucks HQ R&D Lab, which is the inspiration for this brand's approach to innovation.

Outside of work, I’ve spent over 15,000 hours in competitive gaming, solo queueing to TOP 534 NA in Valorant, TOP 1279 in The Finals, TOP 90 in Minecraft Hypixel UHC, and TOP 0.4% in Destiny 2
