The MX Brown's bump is light and subtle; the U4T's is much stronger and cleaner, with a far better sound, a clear enthusiast upgrade.
The Oil King is a smooth linear; the U4T is the tactile counterpart for people who want a defined bump with similar thock.

Quick Summary
The Boba U4T review consensus: it is the tactile switch enthusiasts recommend when someone outgrows Cherry MX Browns. Gazzew’s D-shaped bump is strong and crisp with almost no pre-travel, and the long-pole stem delivers a deep, thocky bottom-out that gives the switch its “T for thock” name.
Specs and Feel
The bump hits early and firmly, then drops into a short 3.2mm total travel with a satisfying long-pole snap. Bottom-out is ~62g (or 68g). Housing wobble is low and the proprietary blend resists the spring ping that plagues cheaper tactiles.
Tuning
Stems and rails ship unlubed (springs are bottom-lubed), so a light hand-lube on the rails smooths the stroke without dulling the bump. Films are rarely needed.
Verdict
If you want a strong, clean tactile with standout acoustics, the Boba U4T is a top pick in 2026. Choose a lighter tactile only if you prefer a subtle bump over a pronounced one.
Frequently asked
What makes the Boba U4T special?
A pronounced D-shaped tactile bump with almost no pre-travel, paired with a long-pole stem that produces a deep, thocky bottom-out. It is one of the most recommended enthusiast tactiles for people who find Cherry MX Brown bumps too weak.
How heavy is the Boba U4T?
It comes in 62g and 68g bottom-out variants. The 62g is the popular all-rounder; the 68g adds a firmer bottom-out. Both share the same strong tactile event.
U4T or U4: what's the difference?
The U4T is tactile; the U4 is the silent version with dampened bottom-out. Choose the U4T for sound and a crisp bump, the U4 if you need quiet.
