content: Timely. I just spent some time today replacing the 18650 in a cheap cordless screwdriver. Variable torque limiting is what the $15 screwdriver has over this device. If it had a vaguely accurate torque limiter in it I think I'd buy one tomorrow.I don't need one. I might however want one.

content: Like everybody here I see no need for this tool, but am consumed with lust. Generally the latter wins out.I don't see what's open source about it though? The links to the firmware aren't even there, let alone source. Main page for this seems to be atwww.raspberrypiwiki.com, but I don't see what it has to do with that, either.Love your videos by the way, count me as a fan!

content: Things like this come in handy if you are dealing with eitherPilot quantities of consumer gear with multiple screws threaded into plastic housings which you may need to disassemble to reflash/rework.Gear containing RF submodules in individually machined housings with a screw every few mm around not only the exterior, but also along internal divisionsTypically while you can get a cordless screwdriver at a home store for $10, it won't have the speed and torque precision suitable for these applications, where things like the $200 Makita kit (or yet more expensive line powered devices you hang with a counterweight from the ceiling) can be common

content: It looks closer to what I've been looking for for ages - something that can do/undo machine screws quickly, while locking the shaft to allow the last tighten/first loosen to be done manually, and being fairly small & light.The max speed of this one does look a bit slow, though better than some others I've seen. I'm not convinced the auto rotation sensing is more useful than simply having two buttons.I've ordered one to look at.

content: Hi,I use this es120 driver every day for several months now and do not regret buying it - very good screwdriver. Nice rotation speed (could be a bit faster) and it is much better than xiaomi wowstick. In fact, xiaomi - is a toy or a present you would never actually use for real work.Motion detection is very handy if you hold something with your three arms and partly with teeth and have to screw it together at some weird angle. In fact I was curious how would this work when ordered and now I must admit - it is extremely handy - just turn the driver with button pressed the way you want it to screw/unscrew.I would buy another one, if they finally will sell an aluminium alloy version. Original one is a stainless steel (very nice finish), but I would prefer it to be a bit lighter.In general - it is the only portable pen-type screwdriver for small work at the moment available. Apart from General Tools one, which is the only alternative (when hacked with li-ion batteries, so it has some reasonable rotation speed or you will fall asleep while using it).I do repair vaping devices and each one is 4 to 14 small screws, so this screwdriver is a huge time saver.Not paid by this company (I don't even know, which company makes it).

content: Initial impression :Look & feel is nice, but would have been better if they could have incorporated internal bit storageButton feels like it's in the wrong place - should be further down - you need to hold it further up than feels naturalToo much free-play when shaft is stationary.I eventually discovered the torque-stop setting by triple -clicking. Seems reasonable but settings are the wrong way round - 1 is strongest, 4 is weakest. Unexpectedly sensible in that torque-stop only applies in clockwise direction.A bit mean that they only incude 2 bits.

(from 1.7)Version 1.8 has the following torque settings: A, P, 1, 2, 3, 4According to the manual 'A' means automatic, and as Mike said above the numeric values are various fixed settings - backwards.Does anyone know what the 'P' setting means? It is not documented in the manual.Not sure if version 1.7 had the 'P' setting as I upgraded the firmware before doing anything else.Only manual I can find is here:http://www.raspberrypiwiki.com/images/9/95/ES120-USER-MANUAL-EN.pdf

Use it all the time and I think it's a must have.So, included bits with any screwdriver is something that is left in the box and never used.

The real value seems to be in the torque setting - good for assembling stuff.I wonder if they'll ever come out with a version that has a switchable gearbox, basically like the ones found in better cordless drills. Maybe it can even detect when it's applying high torque and automatically switch to the high torque mode. Or somewhat easier to design could be a miniaturized impact driver powered by a tiny BLDC motor.

(I literally only know one engineer - out of the thousand or so I have seen in real life - who is even skinnier than her.) Hence why heavy objects seem to be particularly heavy for her.At the risk of going off topic, I'd like to know where you got even "better" videos of "models" working on electronics stuff. The closest I know of was one of my friends "live streaming" how to set up a Bitcoin miner back in the day and how to use a Bitcoin wallet to send her some tips. (I didn't actually see that, just heard about it.) Unless you're saying that she shows off too much and you prefer a more modest presentation.

content: Quote from: NiHaoMike on January 04, 2018, 06:10:34 amI think using it to take apart a 3D printer may have been a little outside of the scope for intended design. Out of all the review videos I’ve seen, and being a creator in that genre she has never came up in any of my suggested videos. How did you find this video, with a specific search?New logo for her might as well be “Don’t turn it on, or you might have to take it off”No thanks, I would rather see the product and it the person in a review.As for the uses, I’ve seen a lot of people cover different reasons on why they might buy Ken, and maybe not buy one. I thing about it last year when I first saw it. But I went the cheap rout as always that usually ends up in a more expensive rout in the long run. One from harbor freight, one from Walmart becjase it was in the shelve, and a few others that hit the trash bucket.My goal was originally to be able to do tear downs and not have my hand cramp and twist in weird positions. Something that happens during the recording (more editing time) that I end up deleting in the end anyway, or I end up suffering later that day/night. So for the person with health issues like a “Stiff Person Syndrome” (SPS), carpal tunnel of the wrist, arthritis, or maybe worse and loss of some fingers I could see this being a way to still do a hobby and assist.Well after a year, I decided to ask for a ES120 (coming soon), I guess I’ll find out if it can help in this area. I gave up on trying to do tear down videos from it causing my fingers to do some weird contortionist bends and lock ups. Maybe this will help?But I’m always on the look out for new technology, lighter soldering irons, anything that can help so I won’t be forced to give up another hobby. But anything labled as medical assistance and this screw driver would cost $1,000 in the US. So I try to stay away from these “medical” reasons for buying or using something in reviews. I’m not in a rush so I don’t see the need for the ES121 and won’t be assembling a 3D printer. It’s more for small electronics with a lot of screws, the repeating of multiple screws is what screws me in the end.Scott

Fix the real problem, not work around it if possible.

content: entertaining vid, but it is kind of a failure of a review.you show plenty of unscrewing but little screwing. you show that torque adjustment exists (1-4 and auto), but you never give us a demo of this. why?i would try to show how it works for various kinds of common fasteners, including screws going into plastic (where overtightening would ruin the plastic). can you get useful and somewhat reliable/repeatable torque for common applications?
