Quite satisfactory for amateur work. Sometimes it requires a double or triple pass over a specific spot to cut all the hairs

The trimmer is not as detailed as I would like. A Philips trimmer I had cleaned better up to 10mm. The trimmer, on the other hand, does not have an extension and does not cut as well as I would like without it. Three stars because thanks to it, I have saved many haircuts. Minus two for the above reasons, but also because until I found a spray that a barber recommended to me for lubrication that does not leave any residues, I had to use its oil... which stayed in my hair and I needed two washes to remove it or a strong green soap.

To make a simple haircut it is good. It doesn't handle shaving very well and it makes an unbearable noise, my ears hurt after use. Also, the battery runs out quickly.

For its price, it's not worth it.
After a short while, the metal burns excessively.
I've had it for 3 months and the charging indicator broke, and even after leaving it plugged in for 2 days, the red light doesn't turn green.
A Chinese one I had before, which cost 10€, was much better.

It cuts incredibly well "like" a professional! I couldn't clog it with anything, it's almost silent and it can also be used for body hair! It won't give you a close shave like a razor, but it cuts VERY close. Nice construction, lightweight, and comfortable in the hand. It works even when plugged in (and it has a fairly long cord). Finally, the packaging was very rich and high-quality, from the heads to the travel case, which had everything inside! All of the above applies to the "big" one because the small one is the opposite... it's terrible: 1st, it takes one AA battery and doesn't recharge it, you have to throw it away! 2nd, it sounds like a poorly made two-stroke engine, three times louder than the big ones! 3rd, it creaks all over and its plastic parts are not very sturdy (like a carnival toy)! 4th, it doesn't have a single attachment, for example, a 3mm head! Apart from these issues... It cuts well and its size is very convenient!

Excellent construction, very good blades, does not get stuck at all and is quiet with a powerful motor though. The blades are detachable for easy cleaning. It has a strong rechargeable battery, if you forget to charge it, it works directly with the transformer as if it were a cord. It includes many colored combs (1.5mm, 3mm, 4.5mm, 6mm, 10mm, 13mm, 16mm, 19mm, 22mm, 25mm, combs for left and right ears) - the mm are also indicated on the machine based on color for easy finding. It also includes scissors, comb, cleaning brush, oil, carrying case.
The trimmer is battery operated and very good for details (favorites, etc.).
Perfect for amateur use - maybe even for professional use.
The only drawback is that it is Made in China, but the specifications are WAHL.

The machine doesn't joke around! It cuts effortlessly without getting clogged. So far, my impressions are only positive.
Attention is needed in cleaning the head if you detach it. I had to watch a video on YouTube to be able to reattach it correctly, but don't let that scare you, it's very easy. I just mention it to avoid mistakes during assembly.
If I buy another machine, I will definitely get the same one!

Update: After two years of use, it continues its work flawlessly!

Without having much experience, mainly due to the quarantine, I bought this specific machine. After my second haircut and after previously trying 2 others, I declare myself absolutely satisfied. I should note that the trimmer operates with a battery.
