I'm taking a chance and ordered one of these.  FNIRSI usually has good hardware but the software is horrendous.
I seem to have a habit of purchasing these mini products.  I don't know why.   :-//

I have a strong dislike for fnirsi stuff. The boxes they make look nice and appealing, and so are their prices, but the rest is such a pile of garbare that you're better off buying some decent stuff.

A lot of reviewers tend to disregard the faults in the fnirsi stuff (they get more stuff for free if they make positive reviews). The problem with this fnirsi stuff is that it is marketed towards beginners, and those are also the most likely to get confused by the flaws in this fnisi stuff. I thin their scope is not even capable of single shot mode. It always does some weird averaging, which is clearly visible when you for example change the timebase or voltage setting. Try to catch a glitch with that. And yet, reviewers still give it a positive review because it is capable of showing a sinewave at half the claimed bandwith of the instrument.

And what does text on the back mean:
"PD and DC transposons Cannot Be Inserted Simultaneously"

I guess it means that all the smoke is released if you put two plugs in this gadget.

A part of the appeal of a power supply like this is it's compact size and portability, and it can be powered from a power bank, but I guess the big LCD would suck the batteries dry quite quickly.

This thing is clearly an "improved" copy of the Alientek DP100 (Dave made a review about that). That is a quite nice powersupply and also relatively low noise for an SMPS. (I think even Marco Reps likes that one).

While having a short peek at youtube, I got a video from Matthias Wandel, and he also gives the fnirsi scope a thumbsdown. He says this advertised as 100MHz scope is "sort of usable" up to around 20MHz or so, and that is apart from it's other flaws such as horrible aliasing.

Maybe fnirsy will stop lying about it's specifications, and either tune down the specifications, or make the hardware and software better, but if they ever do that, I guess that will be 5 to 10 years into the future.
For the short term it's much better to save up some money and buy something that at least matches it's advertised specifications.
