content: Product Info:http://www.miniware.com.cn/?product-244.htmlOut-of-Box ExperienceES120 somatosensory screwdriver is designed andmanufactured by e-Design, and the mainhighlights of this screwdriver are itsexquisite metal shell, OLED display, somatosensoryturning and multi-torqueoptions, these highlights are integrated together into a piece ofcraft-levelmini power tool.Performance ParametersWith weight of 130g, built-in 3.7V single-celllithium, no-load maximum speed of 170r / min,torque up to 2.5 / 20kgf-cm, useof 4MM hexagon bits; and you can manually upgrade the firmware.A portable storage bag is presented with the tool,ES120 can just be fitted in. Only the spacefor carrying screwdriver bits is alittle less, there is still space next to it, and you can DIYin spare time, itis expected to insert 10-12 screwdriver bits.AppearanceThe body of the tool can be described as exquisite,the hard texture of alloy shell is betterthan that of aluminum, making thetool more durable.Let's get into more details of the appearance, itsreticulate knurling plays a non-slip role andensures that the hands won't bepricked. The performance of ES120 in the details is not inferiorto thehardware of other major brands.On top of ES120 screwdriver,is the charging interface and also the data interface, the firmwareof thescrewdriver can be updated through connecting to the computer. If there isrequirement foran upgrade, you can connect the ES120 screwdriver under offstate to the computer, press andhold the ES120 button to copy the firmwareinto the USB flash drive.The specification ofbit socket is 4mm, which can be compatible with a variety of 4mmhexagonalbits, with strong magnetic adsorption. With self-locking device, you canmanually usethe screwdriver, in case of firmly secured screws which cannot beloosened under electric mode,you can manually loosen and then enable theelectric mode.FunctionsWhat is distinguished about this screwdriver is toachieve the direction and speed controlthrough the built-in gyroscope, theadvantage is that it is unnecessary to set a mechanicalturning switch for thetool body, all the functions can be operated with a single key, and canachievethe magical somatosensory control effect. Press the button for three times topresent the5-speed option menu, where you can adjust the torque, commonly use1, 2, 3 and 4, Gear A is forthe automatic mode, the speed of the screwdriverincreases as the rotation angle increases, thespeed of screwdriver bit can becontrolled through slightly turning of the tool body.Somatosensory Control for Direction of Rotation ofBitsOnly by pressing and holding the button of ES120and turn the screwdriver itself as rotationaxis, the rotation direction of thescrewdriver will be consistent with the direction ofturning. As for thetriggering angle of rotation, the minimum control sensitivity is 2degrees,that is, as long as the screwdriver is turned for 2 degrees, the controlcircuit can betriggered.ES120 screwdriver provides a customization for thisfunction, access to the USB data cable underoff mode, short press the button,the computer will identify the USB flash drive; openconfig.txt in the USBflash drive, showing the following contents:StartAngle=2 # (2~10) start angle of braking, if itis set to 2, then the press button willrotate for 2°Gear=4 # (0~4) The set gear upon starting of themotor, 0~4 corresponds to Gear A~4MotoTimeCont=0 #ReadOnly Motor use time, cannot bechangedVer=1.1 #ReadOnly Version number, cannot be changedThe following figure shows the control for turning,the gestures for control in the figurechanged more obviously, this was tobetter demonstrate the control effect, in actual use, youonly need to turn thescrewdriver very slightly, the response will be very sensitive.Thisscrewdriver has a memory function, press and hold the button under the standbyinterface,keep stable for half a second, the screwdriver will rotate, and thedirection of rotation willbe that of the last use; this function is veryconvenient for the users of frequent use of thescrewdriver.Somatosensory Control for Speed of BitsGear A is for automatic mode, in addition toachieving somatosensory control of rotationdirection, it can also achievesomatosensory control of speed, the main role of this function isnot forshowing off, it can not only guarantee the speed of driving, but also canprevent thethreads of screw from being broken.Look at the demonstration in the figure, although theaction is still exaggerated, the actualrotation sensitivity is of about 2degrees. The speed control process is very interesting, fromslow to fast, youcan do whatever you want, it is more like manually turning themotorcyclethrottle. When the ES120 is turned at the slowest speed, the rotation speed ofbit isadjusted to the minimum, and if the speed of turning is increased, therotation speed of the bitwill gradually increase.If you want to useES120 smoothly, the two screwdriver bits presented together with the toolarefar from enough, it is necessary to buy a multi-function bit set kit.The genuine parts areprecision bits of "Labear", a Taiwan brand, made of 8660Nickel-chromium-molybdenum alloy steel with high hardness, the bits areslightly magnetic, such magnetic maycome from part of the screwdriver bit basewhich has strong magnetic force, in short, it is easyto use, you can use thisfunction to absorb screws, the absorption is good, it can help you savetimeand effort.PurposeWith the multi-function bit set kit, ES120 can almostbe used for the entire digital sector: thelens, the players, mobile phones,etc., ES120 can be used wherever there is a screw.Here are a few commonapplication scenarios to illustrate the use of this screwdriver, themajorityof mobile phones on the market, including Apple phones, most screws for mobilephoneassembly are TORX screws, such screws are more sophisticated, although ofsmall size, but canhave around 20 threads, to tighten or loosen them manuallyone by one would be quite laborious,especially for maintenance professionals,handling such screws every day can be considered asphysical labor.Phillips screws onmusic player can easily have broken threads, especially in case thatthescrewdriver bit is harder and does not stop rotating in time, the more powerfultorque willdrive the bit to rotate a few more turns, which may destroy thescrew.As for the slot headscrews on electronic watch, the advantage of having many screwdriver bitscanbe reflected now, no screw cannot be unscrewed, such screws are of very smallsize and arealso used on the glasses.Potential MiningAs for the electric screwdriver, torque is the datathat will be most concerned about; the dataparameters proclaimed by themanufacturer cannot well express its power, the torque value cannotbe learnedthrough tightening the screws either. I personally feel that drilling is theintuitivemethod to show and verify the torque.As differentmaterials are of different densities, the minimum torques required to drillthem arealso different. The following example is to drill wood with ES120screwdriver, as the is veryshort, we find a paint brush with diameter of 1 cmto use for this test, the brush holder isvery hard, ES120 can easily drillholes on the wooden brush holder.Drilling Iron SheetIt is also very easy for the screwdriver to deal withmetal can, adjust the torque to Gear 4,press the body of the screwdriver with force,in the whole process, accompanied by the frictionnoise of drill bit and metalsheet, the drill kit is rotating, while the motor does not enableoverloadprotection due to too much resistance, it can be seen that Gear 4 is enough tocope withsuch metal sheet.Double-sided PCB Multilayer Circuit BoardAs for DIY of circuit board, you need to manuallydrill holes in the CCL. ES120 can easily drillthrough such double-sided PCB ofhigher hardness, which shows its significant motor performanceand drivemodule, the quality of the tool is very applicable for the DIY enthusiasts.ConclusionEach tool will have its specific use, and the use ofES120 is only targeted at small sizescrews, it is suitable for assembly anddisassembly of a variety of sophisticated smallequipment. It has the followingadvantages: small size, high torque, exquisite shell, adjustabletorque andsomatosensory control. Hope thisscrewdriver will become the classic in the classicDIY tools.

content: "somatosensory"? "Of or pertaining to the perception of sensory stimuli produced by the skin or internal organs"It apparently absorbs screws too. Maybe that's the sensation they're referring to...

content: It's clearly referring to the use of the accelerometer to set the speed and direction. While unfamiliar in English, the term isn't wrong.This feature is found in some larger drill-drivers from DeWalt and B&D.

content: I was waiting for review of ES120 here for a while, but nothing came out. I have bought from Taobao but going to take a while to reach me through sea. They also make TS100 soldering iron (probably one of the best portable soldering iron, reviewed by Mike Harrison before).

content: I have one of those, and the mechanism surprisingly makes quite some sense. However, my ES120 has a defect in the socket that takes the 4mm bits: Normal 4mm hex bits cannot quite be pushed through to the magnet as there is a circular ledge in the way, so they don't stick. (The magnet is powerful enough; this is easily shown by putting in a bit upside down -- even the small tip will stick to the magnet quite well.) The bits also wobble a bit too much for my taste (as also can be see in the video above).
