Frequently asked
How is the Jellyfish Y different from the tactile Jellyfish?
The "Y" is the linear cut of the Jellyfish line — same housing and look, but a smooth uninterrupted stroke instead of a tactile bump.
What does it sound like?
Clacky and bright. The full polycarbonate housing keeps the tone sharp and poppy rather than deep or thocky.
Does it need lube?
It is decent stock, but a thin 205g0 pass smooths the slight polycarbonate texture and richens the clack — a worthwhile cheap upgrade.
