prima, the slightly larger rounder Mouse for boys or medium-sized hands, quickly in games and functional in applications ...

The Optical Mouse Zealot for the Game - by VicTsing® comes well packed into the house with an instructional sheet (in English).
It has the usual buttons (left, right, mouse wheel) 4 other functional keys.
The attached USB cable is about 150cm, covered with very long tissue and is very sturdy. As the mouse itself also.
From our PCs / laptops with Window's Vista and Windows 8.1 was detected quickly and without problems (plug & play). Super fast and well it works on a dark Mousepad.

From the size (about 12cm) ago it is best suited for medium-sized hands. Its surface feels pleasant.
It does not slip thanks to the rubber. It is good really good in the hand. And makes the round shape does the hand even during extended use well.
All buttons are easy to reach and easy to operate.
Only the wheel is compared to other mice, which I use, a little too stiff and rattles a bit when turning. But but the buttons work very well and have a slight pressure point they show with a gentle clicking sound also. If one is accustomed as a gamer then you need this as well. Otherwise the confirmation is missing.

The operation is easy and very good.
Built different colored LEDs have a color change in the operation, and show through various color modes as the set high DPI is:
eg red 1000 dpi to 5500 dpi yellow. My favorite setting is the medium blue 2400 dpi.
Disrupts one of the color change, you can press the lying on the side forward button (a few seconds) and a color (your choice) set.
In addition to a simple PC mouse - there are 3 easy-access buttons on the left side.
There would be still the forward and backward buttons that serve you well in a lot of programs, and the Web browser, for example, in the preview pictures.
And best is the front additional Fire-Key (fire button). Who like me feel free schnetzelt through games with swords and other weapons, will know this to appreciate. It is much faster than the left mouse button and helping a fine. You get a lot less quickly a tired fingers and not failt so fast in busy fighting with many opponents.
But you can also use it as a normal left mouse button.
Macro functions it has therefore not is not programmable.

Conclusion: the Super Small, or better slightly larger. It lies well in the hand and is well made.
Connected quickly recognized super fast, has a long rugged cord and many functions.
In addition to switching to 5 different speeds (with color display), it has 3 super well-functioning Extra keys for next and previous. And my favorite as a gamer on the PC, the quick-fire button.
