The web cam is very lightweight, which causes its cable to "pull" it towards itself. There is no non-slip material on either the web cam or the base. The base did not work for me at all, I cannot attach it to my screen. There is a small red LED that indicates that the device is powered on, which bothers me (it distracts attention, there is a small light in your visual field). The image quality is okay. It's obviously not crystal clear. There is quite a bit of flicker and graininess. My main issue is with the lens angle. It is very small, the frame is very zoomed in, barely fitting my face in the frame. There is a slight delay in the image. It does not come with any software, you just connect it.

Information in case it is used through OBS Studio:
It is recognized as "HD 2MP WEBCAM". You can change the exposure and anti-flicker settings. 25 and 30 FPS. 480p, 720p, 1080p resolutions.

Placement idea: using double-sided tape or velcro adhesive tape for detachable placement.

I bought it because I was specifically looking for a cheap camera for video conferencing and it was priced at 9.99 €. It is supposed to be plug & play on Windows 10, but only when I entered the Windows camera did it appear to be working.
What do I mean? It never displayed the message that the device is ready to use, there was no sound of the USB connection in half of the computer's ports, and of course, the second light (presumably the blue light on the right side) either works during a call or when it is simply connected to the PC, only the red light on the left side turns on.
The microphone is average (I didn't expect anything else).
So yes, it works fine and will help me with the work I need it for, but it is not worth even the 9.99 € it cost on sale.

The base is great. I bought it and it has a very good picture. I didn't test the microphone much, only once and it had decent sound. It's worth it for up to 15€, value for money.

For the 10€ that it was purchased on offer, it is more than satisfactory! But for the regular price of 26-27€, I don't think it's worth it. However, it didn't take even a click to start working, as it was recognized directly by Skype, Viber, Zoom, etc. The stand is average, but it does its job

Everything is fine until you go to install it. From there on, everything breaks. Terrible stand and very difficult to use. The image quality is good for its price. In low lighting, it needs support from a LED strip or a small light. My only complaint is the support base

Very good performance even in moderate lighting. It is Plug n Play on Win10. It was immediately recognized by Skype and Teams.
The base is of mediocre quality and I think it loses quite a bit there. You have to do some "acrobatics" to secure it.

In general, a pretty good camera. No need for drivers, the system (Windows 10) recognizes it directly, as do most applications (Skype, WebEx, Viber, Messenger). The image quality is much better than I expected (for the 28 euros it costs), the quality does not deteriorate in low light conditions. The support base is convenient and stable on a computer screen as well as on the back of a laptop. The cable is 1.5 meters long and quite durable (it won't break even if it bends or gets twisted). The microphone is not good, it produces a lot of echo regardless of the room. In this case, I use the headphones' microphone, so it doesn't bother me. For its price, it is a very good camera IF you don't care about the microphone.
