The machine is very good for its price. It hasn't given me any issues and I have used it about ten times. It has scales of 3, 6, 9, and 12 millimeters. It doesn't work for shaving, but for simpler haircuts or to take it all off, it's perfect.

I made the first use for haircut and beard trimming and as a first impression I would characterize it as excellent. I have been cutting my own hair for over 10 years (with a machine and scissors). I have tried battery-powered machines and corded ones. This specific one is powerful, doesn't clog, doesn't pull, doesn't injure, and doesn't make noise. You will hear some people talking about vibration in hair clippers. It is logical to exist, as corded machines operate with a pulsating motion.

I had the Wahl Home Pro 100 (24 euros), the supposed perfect brand and model of hair clippers. It was rubbish, it gave me a lot of trouble. The First Austria is much better and at a much lower price (8.90 euros). However, I will come back in the future to update my evaluation.

Update: 5-6 months later, my review remains the same.
Update: shortly after the first year, it broke down while its price increased to around 12 euros. Therefore, my evaluation now drops it from 5 to 4 stars.

P.S. There is no reason to buy battery-powered clippers (unless you want to cut your hair on buses), they run out of power over time, they are more expensive, less powerful, easily clog, and almost never charged when you need them.
