From the first day, the chuck loses a bit, resulting in trembling when the rotation speed increases. Within the first two months, the second speed broke, then after a year, one battery broke, and in two years, the charger broke. I went to fix it, and everyone says the same thing... don't buy Einhell

I have had it for 4 years already, I don't give it particularly hard use and overall it hasn't suffered anything at all, it works like the first day and for whatever I have needed, I have easily done my job.

The batteries broke and there are none available. They lasted 6 years with light use. It is durable, convenient to use, lightweight, but the batteries disappointed me.

UPDATE 31/1/2021
- The chuck is a problem for some tasks, especially precision drilling. I also suspect that it makes the drill bits break more easily.
- Out of curiosity, I opened the battery to see what it contains. It consists of 3 18650 batteries in series, 1500mAh each. These batteries have a nominal voltage of 3.7 volts, so a total of 11.1 volts. This is different from the advertised "12 volts" and I suspect that the motor is 12V. However, what can you do when the voltage that powers it is 11V or even lower?

For hobby use, it is very good.
Much more powerful than I expected. Relatively good build quality, the chuck rotates slightly off-center but it doesn't create a problem. Quite comfortable in the hand.
The battery is sufficient, it has never run out on me in the middle of a job. It also charges within 1 hour.
