After a year of purchase, I ended up with:

-The machine is very good for amateur use and not professional. For its price, I consider it very good, it does its job easily and to a large extent satisfactorily. I mainly used it for trimming at home and I was quite satisfied.
-The battery is very satisfactory, but not as a professional one, but that didn't disappoint me. I knew beforehand that it would be like that. The good thing is that it can be used while it is being charged.
-The construction for 23€ (when I bought it) reminds me of an expensive machine worth 100€+ and not 100€+. In some sunlight, fingerprints may appear, which doesn't bother me.

In summary, the machine is perfect for someone who wants to use it at a hobby level at home. The only thing I can't determine for sure is the reliability of the machine. I used it about once a month, so I can't be sure

It does its job but it is metallic and very heavy. It didn't suit me. Personally, I switched back to Philips within six months of use. It's not worth the 20-30 euro price difference in my personal opinion.

The machine is fantastic for its price, although it doesn't have a very sharp blade, it is perfect for amateur use and very cheap. I recommend it without a second thought, I have been using it for a while and haven't had any problems. The only drawback is that it has a very loose charging port, it doesn't lock and easily comes out if someone tries to trim while it's charging. It also doesn't have enough settings, but with this money, what else can someone ask for...

Get it with closed eyes. It costs as much as two haircuts and you can get a haircut without an appointment at home in your pajamas.
I use it for shaving as well and it leaves a one-day stubble look just the way I like it. Haircut and shave in ten minutes at most. Very fast and powerful.
A similar branded wireless machine costs 150.
One of the best money I've ever spent

It is not perfect but it serves amateur needs and delivers decently for the money you give, I am satisfied. It performs well on both beard and hair. One thing needs attention and I say it as a serious tip. When shaving mustache, etc., do not go against the grain because it will irritate and sting your skin. Going with the direction of the beard, that is, from top to bottom, will be fine and you will not have any issues.

So far, very good. Completely metal construction, low noise. I recommend it for both trimming and cutting

There is absolutely nothing to envy from the magic clip!
I highly recommend it for both mustaches and fades.
It is worth much more than 25€

I was the owner of various Philips and Wahl products, which to find a machine of this level you needed at least 60€. This one, with only 25€, does the same job and even though it is probably Chinese, it seems quite qualitative. I haven't found anything negative so far in the 6-7 haircuts I have done. It doesn't clog and it has a lot of power for a wireless one. It also has a screen that shows the remaining time until it needs to be charged again. The blades get quite hot after prolonged use and it would be good to let it cool down for a minute at some point before continuing. However, for 25€ it is reasonable, since I have encountered the same thing in more expensive machines (Wahl).

The machine is very good, I must say. Personally, I don't like the combs, if you get or have Wahl combs they will get stuck. The main use I make is for fading and it does it very satisfactorily. The motor is a beast, the cutting is very good, premium feel construction. We'll see if it will withstand time or if it will abandon me randomly.

For less than 30 euros, it has incredible quality. It competes head-on with the professional Wahl 1919, which costs 6 times as much.
If you want it for amateur use and have no experience with professional machines, take into consideration that it has significant weight - something you are not used to from amateur plastic ones.
