The UP who had the pain of the egg came again. This time, the model is a model that DELL currently sells most widely - KB212. The model name of this keyboard is really a little bit interesting. After reading the UP main N phase, you should know that the DELL keyboard is used to a keyboard to find several foundry production. This keyboard is no exception, there are SK- 8120 and KB4021 of Dongju Electronics Foundry under the company's subsidiary, but these two models can only be marked on the back of the keyboard with an ant-like font. All the labels on this keyboard are called KB212, so when you touch To two KB212, if you feel worse, do not be surprised because it is produced by two foundries. In fact, since DELL keyboard was written for so many periods, there is only a slight difference in the feel of different foundries. The KB212 is really a hundred thousand miles. KB212 this keyboard is actually not only black models, there are more rare white models, personal feel white though easy to dirty but really much better, this time UP owners took three KB212, respectively, black KB4021, white models KB4021, black SK-8120 (This is the SK-8120 is actually used by my mother, in order to write the original to the demolition, the results the next day my mother wanted to see the stock found no keyboard, UP main points were cut people Stick, UP Lord: Mom! Have something to say! Let's put the kitchen knife down!).
The following picture sequence is white KB4021, black KB4021, black SK-8120.
Years of corrugated paper packaging, KB4021 packaging printed on the back of the model and foundry, Primax is the Zhi-Extension Technology's East Poly Electronics. The SK-8120's box was long gone.
White is the A00 version shipped out in May 15th, and black is the A01 version shipped out in February of the 14th.
Black and white
Appearance of the same three keyboards, all US 104-key layout.
KB212 follows DELL narrow border design style, the overall look very capable, because KB212 is a short-key design, so the keyboard is very thin.
The new model symbolic concave engraving LOGO.
DELL new model uniform style indicator.
The picture above is KB4021, the picture below is SK-8120. It can be clearly seen that the screw holes are different, indicating that the two foundries are producing molds on their own.
All three keyboards are produced by Celestial. From the label, we can see that the models are all KB212-B, but they are actually different foundries.
The real model must look from here.
The screws used by the two foundries are different.
There are five non-slip mats on the back of the KB212, especially the top two area thief is large, it is worth saying is that there are also non-slip mats after the feet open, DELL really do in the non-slip area in place.
The KB212 uses a side-opening foothold that is moderately elastic.
The UP master always feels that the SK-8120's foothold is a little longer, and it takes a caliper to measure it.
Although the two keyboards use a short-key process crater design, but the structure is very different, we pay attention to look inside the plastic wrist will find that even though the structure is different, but the shape of the plastic wrist missing the same, but the two generations of KB212 The factory's rubber wrist is a hundred thousand miles away. Simply speaking, KB4021 is a raised attack, and the SK-8120 is undercut.
The difference in structure is also reflected in the keycaps, and it can be seen that the SK-8120 on the right is significantly shorter than KB4021. In fact, the SK-8120 is also much shorter than the KB4021.
The keycap material is ABS, and the font uses a silk screen transfer process. Both of the particles are delicate and the handle is slippery.
Cap wall thickness is about 0.6mm, white models are slightly thinner.
KB212 ultra-thin design also does not use ergonomics, uniform height keycaps.
The slim design of the narrow frame makes the KB212 very compact.
The change of the tilt angle after the kicker is turned on is not very large, and the height of the SK-8120 is slightly higher than that after the kicker is opened.
The wire diameter is about 3.1mm, and it is fine.
KB212 uses a USB interface without magnetic rings.
Three keyboard weights are white KB4021 = 560.7g black KB4021 = 558.4g SK-8120 = 539.6g
About the KB212, the two main founders of the UP, said that there was a huge difference in feel. Although the appearance is the same, but the two foundries are using their own mold this point can be seen from the back of the keyboard drain holes and screw holes are different, the keyboard in the past even if the different molds of the foundry are different even the shape of the crater It is also different, but its plastic bowls are not the same, but this time the KB212's two plastic bowls are just a hundred thousand miles away. The rubber bowl of KB4021 is a raised attack, while the rubber bowl of SK-8120 is the middle. Concave guard. Similarly, the difference between the two keycaps is also huge, we can see that KB4021's keycap roots are significantly longer than the SK-8120. In actual use, the KB4021's keystrokes are significantly longer than the SK-8120. Feel SK-8120 and KB4021 simply go to the two extremes, SK-8120 key process is very short and feel very soft, paragraph sense and rebound are weak, and KB4021 key process is slightly longer and feels hard, sense of passage and rebound The force is clear and powerful, but then both are short-key processes so UP does not like it. In addition, the SK-8120 is clearly winning on the stability of the keycap, and the KB4021 is swaying. Therefore, the SK-8120 performs very well in terms of quietness, while the KB4021 is less satisfactory. Finally speaking about the use of materials, KB212 also has the problem of non-magnetic ring, no ergonomics, thinning of the wall of the cap, thinning of the wire and other materials.
If you need to purchase, please pay attention to the version is KB4021 or SK-8120, the difference between the two feel great, or buy it according to personal taste it
