No USB Type-C in 2019 is an instant no-go. Just stop with microUSB. J U S T S T O P

jantariStop with the current year crap. It's asinine and meaningless. J U S T S T O P
Though I'm totally behind the USB Type-C part.

Hey MD, why are you guys always getting these screwdrivers and soldering irons from distributors like SEEED and SainSmart, when they are designed and manufactured by the same Chinese company selling on Banggood for their original, lower price?

I have the older version of the tool, the ES121 with a slightly lower torque motor, but otherwise entirely the same.
If you do a lot of work with electronics and this thing is AMAZING. The build quality of the tool itself is high, and it has worked consistently with not a single bug or issue in the ~1 year I've owned it. It makes building drones a breeze, and lowers overall build fatigue by a lot.
PROS: High build quality, solid in the hand Long battery life. Extremely intuitive on how it works Just freaking works, consistently!
CONS: Button placement is too high, it's ergonomics could be better with the button placed further down the shaft of the tool as if you were naturally gripping a screwdriver Even with MD pricing, it's still pretty expensive. It's thicker than a standard screwdriver, you might need to run an extension to get into tight spots or deep screw holes. I noticed an ever so slight wobble in the drive shaft, meaning it's not perfectly straight (Doesn't really affect usability, but it's not a cheap tool, for the price you pay it certainly should be straight)
All that said, I would not hesitate to buy one of these again, or even upgrade my ES121 to the ES120. It's such a simple little tool, but if you do a lot of work on small electronics it's irreplaceable and will save you more time than you thought possible.

DrKhanMDI came here to say the same thing. I love my ES120, it's super handy when you have a lot of screws that aren't super tight.
It's pretty good for laptops. I use mine on my 3dprinter.

I don’t know which came first, but he torque level is different between the 120 and 121. Age is immaterial, however, as they are different products for different purposes.

Huh? So Massdrop are selling it for more than $44.99 like the MSRP?
Edit: Looks like Massdrop had the wrong price and they've now updated it

deanpcmadApparently MD messed up the MSRP. Sain Smart has it listed at $99.99. https://www.sainsmart.com/dev-boards/electric-screwdriver-stainless-steel-screwer-smart-motion-control-screwdriver.html

For those of you comfortable with ordering from the Far East, Banggood has this (ES121 model) on a "flash sale" for US$86 with free shipping. Sale lasts another 2 days.

You can choose between Chrome and Stainless finishes (I think MD is only offering stainless), and I haven't compared the included bits.

Here is the diff:
ES120/ES121
Price: $90/$110
No-load speed: About 270 rpm/380 rpm = 4.5 rps / 6.33 rps
Maximum torque: 30 kgf.cm (manual mode) / 1.5kgf.cm
Gearbox: integrated planetary gearbox 1:144 / 1:64
That max torque difference doesn't seem to match the gearboxs, I'm wondering if the ES121's is non-(manual mode).
Anyway, when they manage to add LEDs I'll think about it...

MichaelAtOzActually the big difference between the them is the electronic torque and the free speed.
ES120: 2.8kgf.cm and 270rpm using a 1:144 gear box reduction
ES121: 1.5kgf.cm and 380rpm using a 1:64 gear box reduction
Everything else seems to be identical, both have a maximum rated manual torque of 30kgf.cm and use the same 25,000rpm motor. Like you said, but their electric drive torque numbers being the same made no sense. I went to the Alibaba and bang good to get the numbers from the 'updated' versions of both. The ES120 update is likely to do with a new bearing setup for the locking clutch.

Just the thing for tightning the wheel nuts on my tractor. Honestly, when dealing with tiny fastners the only torque sensing tool I would trust is the dextrous human hand.
