Incredible tool. I use it professionally. It doesn't clog, it's flawless. Just two things. It doesn't have a charging indicator light or a battery level indicator, although you can hear it when it discharges that it drops. Which isn't really a problem to be honest because it has amazing battery life. Personally, I get over two hours of continuous use. The blades do heat up easily, of course, but this can be fixed with a pair of Wahl blades. The machine costs 15-20€, you add a set of Wahl deep-cut blades, and it performs incredible fades. All Wahl guards fit without any issues. You can also use its own blades, but they do raise the temperature, especially after a lot of use. If you have a cooling liquid to spray on it or some alcohol to dip it in, it cools down, and you can continue just fine. I recommend it for both professional and amateur use. Mainly for colleagues who are just starting out or for someone who wants to groom their beard for 15€, I don't think you'll find anything better. Even with 50€.

You won't believe it, but the machine is still working after two years in a barbershop. I bought it again a couple of times, recommended it to friends... I experienced it firsthand, opened it to clean it... So the first problem that arises is the on-off button quite soon, meaning after three months the button starts acting up... It doesn't leave you in the middle of a haircut, it just might need a little push to turn on... I changed the button and put one from another machine, and it still works perfectly.... Recently, after two years of continuous use, the poor thing started to ask for a battery. It barely managed a haircut and would discharge.... So I got a battery from an electronic cigarette, 3.7v 2200ah, exactly the same it uses, and I put it on... Like new, we're talking about an amazing machine.... It does haircuts all morning, charges at noon, and does more in the afternoon..... But I have to take care of it.... To not let the blade heat up too much as it transmits internally and burns everything... Rinse with alcohol, oiling, and cooling with special spray.... There for two years, it hasn't made a peep... It's worth noting that it works with some blades from an old Wahl I had since 2017, and it still cuts and doesn't make much noise....
