I bought this machine 9 months ago, it does a very good job, I would say it is worth it. I have been cutting hair as a hobby for the past few months and I often buy cheap hair clippers, but they all break. I bought this one for 60€, which comes with Wahl premium guards, which are the clips that go on top of the machine. It comes with 6 guards:
1. 0.5
2. 1
3. 1.5
4. 2
5. 3
6. 4
I recommend it to hobbyists as well as professionals. If a teenager like me wants to buy it, I think they will be satisfied. The machine needs oil after each haircut, so it would be good to get a bottle+. The battery lasts for 3 haircuts, about 30-45 minutes each.

So I bought it a year ago ...
In 4 months the on/off broke ...
I went, they serviced it, and after 3 months the same thing happened again ...
Then they replaced it ... and in 5 months the same thing happened again ...
Don't make the mistake of throwing away your money ...
Don't even trust it for work, especially its performance in fade haircuts is tragic. It bothers you 10 times more than normal.

The machine is quite decent and has plenty of extras, such as premium guards and two clippers. One fade and one taper. The battery is quite good and the weight is ideal. The only downside is the charging cable, which is short. The company is Spanish.

The machine is quite good in terms of performance, although I haven't used it much yet, but it has some issues: The first and main issue is that the levers for adjusting the length are a bit stiff and made of plastic, which doesn't impress me and I hope it doesn't break. The plastic on the combs also seems a bit mediocre, although it's similar to Wahl's premium ones in other aspects (although they don't fit well on Wahl). Finally, the charger cable is short and inconvenient for using it with electricity. Of course, the manual also says not to use it anyway...
Update: After a year of use, I consider it quite good for its price. The issue with the lever that I mentioned in the initial review is no longer a problem, and its performance is very good. The main negative point I find is that it came with 2 sets of blades in the package. I tried one once and it heats up very quickly, and when you attach the combs, the noise is quite annoying. I think the design of the other set is not very good when using the machine without combs. They are sharp, but I don't think they easily catch the hair. Nevertheless, they do their job.
