OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum tolerances for maximum air pressure
Silent Wings 4 120mm PWM high-speed makes for extraordinary air pressure and, therefore, significant increases in the system’s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM high-speed allows the user to run even the most demanding applications.
DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 120mm PWM high-speed has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed.
6-POLE FAN MOTOR
The key for virtually inaudible operation when needed
6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
in mid-speed.
FLUID-DYNAMIC BEARING
For a sustainable operation
The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of
Silent Wings 4 120mm PWM high-speed.
ELEGANT LOOK

Love it
I’m honestly impressed with this mouse. The Wireless Optical Mouse works exactly as it should—simple, reliable, and smooth. Setup was instant, just plug in the USB receiver and it’s ready to go. No lag or connectivity issues at all.
The tracking is precise, and it feels comfortable even after long use. The battery life is solid, and I like that it goes into sleep mode to save power. It’s lightweight but still feels well-built, not cheap.
For the price, this is a great value. If you need a dependable wireless mouse without overpaying for unnecessary features, this is a perfect choice.

Awesome quality mouse
Fantastic value. First it feels like a quality mouse and works like a mouse 3-4x the price. It is solid and has nice weight to it, not like some of the flimsy competitors. I am buying another just to have.

Great Mouse
I normally use the Logitech M325c. I've gone through dozens over the years. It works very well, but they seem to wear out fast; the wheel scroll is what fails. I decided to give the Amazon Basics a try. So far, it looks, feels, and functions the same as the Ltech; it doesn't have the fun colors, but if it holds up longer than a year, it's a fair tradeoff. I will revise this review if things change in the future, but as of now, I would recommend the Amazon Basics and will replace the other Ltech's when the time comes.

Works great!
Color: Blue
The mouse gave me a little trouble when it was in the back port of my pc tower, but worked perfect when i plugged it into one at the front. The light was flickering for "low power" despite new batteries being in it, but worked great after playing with it for a few minutes. The mouse is really easy to work with and is silent, which is nice when you're in an atmosphere with other people. I found it fit well in my hand and didn't cause any discomfort. i believe it to be reasonably priced for the design.
