Entry-level Gaming Mouse Many brands favor small mice for better control of cost, better applicability, and simple and reliable structure. These reasons make this type of entry-level gaming mouse the largest share of the gaming mouse market. part. Logitech's entry-level gaming mouse products have had excellent market feedback from the MX300 fifteen years ago, especially in the ten years that the gaming industry has been thriving. From the previous G100S to the G102 introduced in this article has been separated by more than three years, at the same time from the current pricing of major channels, G102 either product or price positioning is the continuation of the G100S position, and at this price level is also a special competition Intense price segments, such as the kinzu v3,rival100, mad snake 2014, and SICA that we are familiar with, are also due to the intimacy of workmanship design of a product in tighter entry-level gaming mouse products where price space is compressed. Peripheral Hall is also a special concern for this price segment product, and I myself too! Here we take a look at whether the G102 design has enough improvements and better competitiveness. Everything is very excited, and I see the body, the long-awaited white g102. Finally got the body, and my heart is very satisfied! The effect of the United States and the United States There is not much mouse in the hand, there is also a large g a snake, compare it, from the volume G102 PRODIGY is smaller than the two mice, but the grip in the hand is still good, but for I have 21 hands long climbers are not much worse, but the G102 PRODIGY button feels really larger g and Python shorter. The beginning and the test use the mouse pad to make a shadow, the cushion basically does not have to use, all regards as the shelf thing haha, happens to point the light effect. ASUS MG50 effect, mat with a fixed rog bracelet, full of malicious Sairui Frost, this mat was not intended for use because it was too thin and slippery, basically as a decoration. Millet aluminum mat, this mat is a lottery roll with 10 dollars, with good use in summer, cool than the cloth mat comfortable, from the placement of the effect is still better to see some of the aluminum mat. The Razer resin mat will come again, because black is cloudy today (fog and haze everyone knows), so the effect is not very good. Finally, the thieves ship table mat which is also a welfare car to return to a Tencent blue diamond mouse, do not even want to open haha. Back home to parents. The madman's table mat was not photographed alone because it was too lazy to clean up the table. After the screws are removed, the upper cover is easily taken out. Although there is no bayonet, it is enough to see that the precision of the die is high and there is no obvious gap. The upper cover is really hard to do, and the tail is very good for light transmission. Because of these Details perfectly embodies rgb lighting effects The springs in the shrapnel position are also handled very well, guaranteeing press and rebound effects. The PCB is structured, and the governor of the Mercury host also uses the master of the g series. Overall, the g102 Logitech is indeed full of sincerity. The tail has a total of 3 shell led lights, which guarantees the luminous effect and the light strip effect at the tail of the top shell. It is indeed very satisfactory. Finally, the performance of the mouse on various mats is attached, but it is sad that the snake is really old. The most stable is the big g, followed by the g102, it seems that the old python is really a bit old veteran. The three lines are in accordance with 1. Big g, 2.g102, 3. Old Viper ASUS GM50 Racer Frost Great snake ants Madman Power on, G102's light gradient is also soft, but the brightness is somewhat excessive, these can be adjusted in the G drive, you can get the brightness value for your own eyes. Logitech's drive adjustment is also relatively easy to operate, including DPI, lighting and other parameter settings, as other manufacturers, are essential options.

In order to prepare to test the G102 PRODIGY, five kinds of mats were prepared in advance, including silky Sensei Ice Blue, smooth game console table mats, control class ASUS gm50, millet aluminum mats, and Razer Giant Ant 2 resin mats. . There is also a pirate ship MM300 mat that has just arrived.
G102 PRODIGY USB interface does not have much highlights, more general Logitech style, and there is no any logo, processing is still good, no neat corners neat. 
Start with a pirate ship 
G102 PRODIGY dismantling really simple, 3 screws to get, there are friends to be removed remember the screws on the pads and stickers below, I was ignorant of the first under a floor mat, I hope someone is walking my detour.

advantage:
1, comfortable grip, ergonomic fit right and left hand use
2. Lighting effect
3, sincere and full of workmanship, no sloppy due to price
insufficient:
1, 7N (10M) micro-touch left and right touch gap is too large, can only wait to change the micro-
2, the roller does not use the shuttle wheel, the sense of damping is sufficient but the sense of scale is not strong
3, for the individual side keys are too slender, need to move the thumb when operating
Product Description
SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.
Surge protective Device Model Selection
With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.
SPD for Power Supply System Series Selection Guide
The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
