The scope review was good. I guess lesson learnt: you shouldn't send Dave a product marketed as a competitor to other professional products, but then with hobby level quality.
That screw driver is a rather special tool made for working on potentially life circuits. So compare this more to an CAT 4 meter. It's a lot about the electrical insulation and less about motor speed / battery. I find it nice to have the supposed maximum torque on the bit's. There is positive side of having such a weak motor: one would not that likely slip on the screw head at the low torque.
The extension part might be for torque limiting (e.g. the slip clutch) and this might be a significant part of the price point.
I am still not a big fan of the implementation.
The Panasonic driver is a completely different tool - more suitable to undo the screws on the instrument and similar, but nothing you like on a life circuit. The isolated screw driver is more about working on a fuse panel or similar.
The doctors recommendation is a little odd. There is a issue with normal screw drivers: if used a lot they put a lot of strain on the wrists and elbows. So they are really not a good idea for frequent use because of poor ergonomics.
It seems the Crowdsupply page for the Haasoscope has been updated with Dave's endorsement
At the moment it shows the data (+/-64 samples around the trigger) from one of the channels, and at startup has a pic of my baby drinking a bottle (see below) - retro cool, eh?
It seems the Crowdsupply page for the Haasoscope has been updated with Dave's endorsementI don't see that. Did they remove it or is there some weird caching going on here?
he should take this review as the raw, non sugar-coated, unadulterated truth, and fix the issues.
After that, he should send the updated hardware for another mailbag. If the hardware works well this time, I'm sure everybody will just forget about all the previous mishaps and maybe recommend it to others as a quite capable poor mans scope.
I would think a typical mailbag item should be 3-5 minutes per item. If a "two minute teardown" isn't appropriate, save the teardown for another video and get on with more of everyone's favorite segment, MAILBAG!

I tried that, and IIRC people didn't like it.
I, too, wondered about the 1KV rating for the screwdriver. I would like to see an example of the use case they had in mind - but even so, what if you are unscrewing something that did need that rating ... and then dropped a screw from the tip.
The format of this mailbag video is just fine for me. Yes, it ended up like a review of the screwdriver, but what's wrong with that? Everything that Dave explained about that screwdriver was useful information! For example, if it was just open it up and fool around a little bit for 5 minutes, we might have not seen the detail about how that screwdriver is supposed to work. It isn NOT a tool to unfasten or fasten a screw from beginning to end. It's just a tool that saves you time when the screw is already loose. The unfastening and tightening is intended to be done with a tightness hand feeling of the user. So the concept and idea behind the screwdriver is quite good! But to realize this, it is necessary to look at the tool more closely, which is what Dave did.
Same thing with the USB oscilloscope. I would have hated it if this was just an "open the box", talk about it a little bit, repeat what the manual already says and then do away with it in 5 minutes. I took in and appreciated all of the extra information that was presented, and so should the developer!
If that were my "scope", I would want to kill you. Poor guy. Surely there are many good things that can be said about it. But no. Not a single one!

LoL ChicagoT - where did you get that from!? Python is used in many large software projects around the world, by a lot of scientists etc...
Seriously though - in terms of the video I thought you gave the items enough time and perhaps this video will end up being an outlier in terms of total run time.
You are correct. This is VDE 603 certified product, certified for use on live circuits. And yes, that extension is THE torque limiter (fixed one) named easyTorque. On their full kit you get 5 of them, for different torque settings. All in all it is specialized, good quality product and expensive for that. And probably not something you would want to buy unless you need it.
