PERFECTING ENGINEERING
Cooler Master’s Mobius 120 is our new series of performance fans. With our enhanced Ring Blade Design, the Mobius Series optimizes both performance and acoustics, catering to a dynamic range of applications from case, liquid or air, to overclocking and intense gaming.
RING BLADE DESIGN (RBD)
Interconnecting fan blades designed for a reinforced and rigid structure, eliminating vibration for stable and fluid fan operation.
LOOP DYNAMIC BEARING
New loop dynamic bearing design utilizes thick oil coating and lubrication to allow for stable performance
OIL REFLOW
The oil flows back to the sealed bearing to create constant lubrication against friction and increases the life span of the fan.
DUST PROOFING
The sealed and concave position of the bearing prevents air and dust exposure and ensures a smooth transfer of motion.
ANTI-SWAY SYSTEM
Magnetic ring prevents bearing shaft from tilting, stabilizing the fan to prevent fan blade obstruction under various orientations, as well as oil spray.
PRESSURE AIR ACCELERATION
Angled inner frame rim with chamfered side vents boost airflow draw, maximizing force induced air pressure and diminishing dead air.
ABSOLUTE ACOUSTICS
Sound output fine tuned to the optimal prominence ratio to achieve sub 6dB noise levels without performance sacrifice.

It stopped working after three play sessions
Size: One-Size-for-Most
I thought this ball was great until a week later it stopped blinking and got lost in the snow. We only played with it for three days for 20 minutes at a time. It should’ve lasted a lot longer.

It’s absolutely perfect for fetch in the dark!
Size: One-Size-for-Most
We needed to find a glow in the dark ball to run our over active dog after dark ( gets dark now about 5 pm ish) I was hesitant to buy this ball at first. We went to try it out and it totally blew my expectations! The ball really glows, it’s a durable rubber and when it hits the ground it lights up blue and red. Incredibly satisfied and just ordered 2 more. If you need to run your dog in the dark, this is absolutely for you. Highly recommend it

Dog loved it
Size: One-Size-for-Most
Great! My dog loves taking it outside at night so he can see where it goes easier. Super bouncy, he has had it for over a year now and still not destroyed. Perfect size for his mouth too and easy to clean.

Light up and glow in the dark ball
Size: One-Size-for-Most
Definitely my girls favorite ball 😀. It disappears and I have to buy another one or she goes nuts. Glows in the dark, brighter with more sun. The bounce light up don’t last a real long time, too quick to quit for her but still loves it.

Durable & Bright - Great for Heavy Chewers
Size: One-Size-for-Most
Pros:
Extremely Durable: Survived an aggressive chewer where tennis balls failed.
Dual-Visibility: Features both internal flashing lights and a glow-in-the-dark "chargeable" surface.
Perfect Size: Fits comfortably in the mouth of a 40lb medium-sized dog. Same size as a tennis ball.
Cons:
Battery Life: Unsure how long the internal flashing lights will last (though it has held up well so far).
