These are really nice, and they provide a stable power source at 3V3 and 5V. However, the switch does not appear to have any effect on the power supplied on the solder pads. As such, I'm not sure the undercurrent protection works when using those. I'm using protected 18650 batteries so I don't really care.

It's a box, simple enough. It opens an closes. You can put stuff in it and take it out at a later time.

Works great. I hooked it up to an ESP32 and in no-time I had myself my very own Bluetooth audio receiver. I haven't yet succeeded at producing my own sine waves, but I'm still fairly new to this i2s thing.

They appear to be in good order. I haven't tested them yet, but they appear to be a good solution if you want to reuse an old PC power supply.

Decent quality breadboards. I mostly use two of them connected (removing one of the power rails) so wider modules like an ESP32 can be fitted across.

This little electronic screw driver looks great and comes with the most important bits for small electronics. This will come in really handy when doing repairs or DIY tinkering. The torque is about what I expected, and strong enough for the most common scenarios. I've tried it with a few devices and for most of them it was strong enough. Screws that are very tight won't budge though. A bunch of useful bits were included in three thin tubes. Both the stick and the tubes can be stored in the cotton sleeve. This is a great device to have within reach when tinkering. Even if you have bigger and better tools, this one is so compact and easy to use that it should be in your basic kit.

This is a nice tiny camera, hardly bigger than regular dice. While the product description claims some kind of WiFi capability, there's nothing about that in the specifications on the box or the manual. So I'm pretty sure this device has no WiFi at all. The camera claims to be able to record to a TF card (that's not an SD card!), but I've only tested it while hooked up to my Linux PC. It works great with V4L2, although the resolution is limited to 1280x720 (yes, 4:3 ratio). I can't verify the camera is capable of 1080p, since changing it using the instructions in the manual appears to have no effect on the MJPEG video stream and trying to change the resolution with v4l2-ctl has no effect either. The USB connector is a bit weird, as regular micro or mini USB cables won't fit. It comes with a cable, so you can get it to work, but replacing it with a longer cable may turn out problematic. It's about the same height as a micro USB but not as wide. If anyone knows what type of connector that is, I'm curious to find out. Anyway I had hoped to get a 1080p WiFi camera here, but actually got a 720p USB camera. Not too bad for the price, but definitely not what was advertised. Still, it works flawlessly on Linux and is compact enough that I'll probably find a use for these.

Right out of the box the focus could not be adjusted and nothing was in focus. The knob just clicked like grinding gears. I opened it up and some component was blocking the linear gear element, so I pushed it back a little bit and closed it up again. Now I was able to focus. The focus knob is too loose though, so even if you get it perfectly right at 4X zoom, as soon as you release the knob it goes just slightly out of focus again. This is not so much of a problem at 2X zoom as that's a bit more tolerant. I could not figure out how to get the focus above 4X though, even though the product description boasts 600X zoom. Not that I'd want 600X zoom with a finicky focus knob and wiggly stand anyhow. The screen has a nice size though, and the picture quality is adequate. In conclusion: it's far from fantastic, though for this price it's a reasonably nice gadget.

It's not super-accurate, but it gives a good indication on stuff like resistance, capacitance and voltage drop. Occasionally it misidentifies three-pin components, but then identifies them correctly when I try again. This is rare, though. It looks cheap, but who cares?

These are super easy to program as they have their own USB-to-serial on board. They also already come with the headers soldered on, which saves a couple of minutes of soldering. However, if you prefer to solder directly onto the board, you'd have to take them off first. Just don't expect these to fit a breadboard though. Or rather, don't expect them to fit and then connect them up to something, since they basically take the whole width of a standard breadboard. However, if you have two of those breadboard where you can take the power rail off, you could fit two of these boards together and place the module across both.

Putting the 18650 batteries in this storage case is way better than having them rattling around in a drawer or other box. These don't come with batteries, of course.
