With the continuous improvement of Android devices such as mobile phones, tablets, and set-top boxes, the performance enhancements and these devices have made it easy to run most of the games on their own platforms, and because of the in-game experience of some devices Relatively bad, so the handle class has become the protagonist of the accessories, Beitong as the domestic first-line smart handle manufacturers have been creating a classic, such as the handle in the Asura series, bat series, Carlo series, Pandora Series, etc., have performed well in their respective use environments. The individual's application of the Beitong D2A wireless is a bat series, a simple appearance has a good experience, the following together to see.
Exterior 
Beitong Bat D2A wireless game controller uses a black packaging style, which is in line with their own colors, in fact, in North Pass most handles are used in this style style, the middle of the display map can give the fastest understanding, the upper left corner There is a shadow version of the night, the lower right corner is the 2.4G wireless and support 360 logo, as the side and back is supported platforms and product inventory information, Beitong D2A wireless controller support windows system, compatible with PC360, PS3, Android and other platforms The basic coverage of the current mainstream. 
The bat D2A gamepad on the accessories comes with instructions, charging cable and NANO receiver. For the three said under their own feelings, the necessity of the instructions is more important, the initial can understand the handle of the four modes of switching instructions; charging line is optional, anyway, all mobile phones are common, the feeling does not matter; NANO receiver is a combination of wireless Used, compact and easy to carry, can be very easy to lose the volume, the handle does not provide storage slot, this is the first point of inadequacy, and now in addition to set-top boxes, many players like the tablet and mobile phone operation, had to drag an OTG line Or OTG adapter, if the manufacturer can put on a micro-usb receiver and type-c interface receiver is perfect, this is the second point. 
The individual used to use the wired handle in the Beitong Asura series. The first impression of seeing the Northbound D2A bat game controller is simple and intuitive. There is no such high-profile appearance, and the key position distribution in the black body handle is more scattered, making The slightly wider shank reduces misoperation, the handle uses ABS material as a whole, and the surface has no mirror-like process. The traditional scrub is more durable, and the key distribution and design feel like an integrated PS+Xbox integrated body. 
The centerpiece of the bat D2A wireless controller is the LOGO of the Beitong factory. It also serves as the mode selection and home page function. Long press to switch between the four modes. The user observes the current use environment according to the bottom indicator. In the middle of the LOGO and indicator lights, four keys are used for returning, setting, eliminating and starting. To assist in the use of the game, the return and start times in the four keys are slightly larger. After all, the frequency used may be higher than the other two. It can be seen that the detail of Beitong is better, as for the two rockers on both sides of the indicator light. The handle automatically shuts off after no operation, so the off button does not matter. 
The bat D2A wireless handle directly below is a symmetrical rocker, the surface of the use of a rubber material wrapped, increased the friction between the rocker and the finger, after all, is still easy to remove the small area of ​​the touch, manufacturers in the double rocker surface Grooves are added to the up, down, left, and right positions. It should also be a double handle for handle and non-slip. The full operation of the two joysticks rebounds quickly, without any hindrance, and the slightly thin edges do not feel the pressure of the operation and feel good. 
The left cross button adopts a mirror treatment, which corresponds to the matte surface forming process. The sliding operation is comfortable. However, the mirror is very easy to contaminate fingerprints and scratches, especially for high-use keys. In the shape of the cross button uses a separate processing, so that the operation is more accurate, while the slight depression of the center also makes the entire button more closely to the thumb. 
The button style on the right side of the handle reminds me of the Xbox. The four keys of the ABXY are also mirror-finished. The sleek feel gives a good sense of operation. In order to maintain a uniform color, no distinction is made between them. For this design, the PS is convenient. And Android games, after all, many settings are Xbox-like settings. 
Four action function buttons set at the front end of the handle, the FPS game defaults to LT/RT for aiming and firing, LB/RB is for switching weapons and other functional buttons, among which the keys of LT/RT are recessed inwards, which is in accordance with the user. The tummy of the finger belly is not too rigid and quick to operate when pressed. The middle position is the handle charging interface. The built-in 500ma battery is enough for the long-term operation of the game. The used micro-usb interface is suitable for regular mobile phone lines. 
Bat D2A wireless controller back ergonomic design, the user's palm habits are properly bent, allowing users to better fit the palm of your hand, brings a comfortable feel and will not have too much fatigue, matte the same Occupies the entire backside to reduce the hand-slip phenomenon after sweating. The middle label comes with simple parameters. If you can add a receiver card slot at the back, it will be perfect. 
The arc-shaped double-grip handle is ergonomically designed. The bat D2A wireless handle is divided into two parts at the entire grip. The panel transitions to a smooth surface. A part of the factory has adopted a subtle matte process and is rounded. The processing, so that not only increase the friction in the grip but also to maintain a comfortable feel, kill two birds with one stone, bat D2A wireless controller support game feedback vibration, attached to the two grips, the effect of the PC is obvious. 
Before the test, the individual first signs off the switched bat D2A wireless controller mode, and the player can also view in the manual. When the switching time is long, the LOGO can be completed, and the personally used is the PC and the Android mode, and the last one is basically not used.
use. 
For the common centralized mode individuals have been tested, the first is the tablet game in the Android series, the test model for the millet pad, the game is "modern war 5", support for the control of the handle makes this game very easy to use, while operating It's also much more convenient than playing directly on the tablet. The response in the game is very fast and there is no delay. However, when the second scene of the hospital is switched, there will be a brief loss. It should be related to the optimization of the game. In fact, the game controller is more suitable for FPS shooting. The game of the series and the King of Fighters series, unfortunately Android compatibility issues many games can not activate the handle vibration, slightly regret. 
In the Android phone is still this type of game, but the game compatibility is much better than the flat, the test model for vivo Xplay5, such Tucao under the North pass, the lack of type-c receiver for a plus 2 and music as the 2 There is no way to use it. The test game is "Wild Bug 8," and the game responds equally well. It is really not as easy as the original model for game controllers. 
The benefits of the native USB interface receiver are PC games and TV set-top boxes. The test set-top box uses the millet box 3 and the test game is "GTA". As a game for transplanting PCs, "GTA" is always facing in terms of quality or story or habit. PC closes, after connecting the handle need to operate several times to adapt, after all, the key bit more than the game in the mode of operation, the game's feedback is good, and the operation is better than the phone handle APP simulator. Personally, it is recommended to install the red and white simulator in the set-top box. First, occupy a small space, the second is to bring no pressure, and the third is to play more. 
Have to admit the PC's perfection, after all, many games are after the emergence of the PC came to Android or ios system like, personal test of the "Dead Space 3", conventional keyboard operation, the key dispersal and feel certainly not as good as the handle Wireless operation on the PC does not require an external small OTG tail, the integration of the game is also very perfect, the operation is very natural, and very quickly, for this kind of request without delay class game bat D2A wireless controller is still good.
to sum up 
Intermittently speaking some of his own feelings and styles of handles, there is not too much hope for a person with a price that is not too high, but it is still a bit unpleasant to mention:
1. The accuracy of the cross button is improved, but the flexibility of the relatively circular eight-direction key is less. Both have their own advantages and disadvantages.
2, equipped with too few interfaces, if you can with type-c, micro-usb interface is perfect
3, the lack of a mobile phone holder, fully equipped with optional handle combination mobile phone holder
For the Beitong Bat D2A wireless controller manufacturers do a good job, the details of the handle is very good, if the accessories can be modified under the perfect, after all, the main push of the Android system flat and mobile phones occupy most of the market, both Performance is also a place for the game. The personal experience that Asura used before switching to the wireless controller is finally out of the wire. The 2.4G wireless operation is mainly convenient for the set-top box games, including the PC360, PC mode, BFM mode and PS3 mode switch to make this handle low The price is not low, the function highlights, the regular game settings do not have much change, simple but easier to let players get started, for my non-professional game player Beitong Bat D2A wireless controller is more suitable for me, feel Easy to operate, dye-resistant wireless black, simple as natural.
