It is obvious that it is not for professional use. It is mediocre in all aspects except for the price, which is low. So, it depends on each person's judgment according to their budget. It needs upgrading in some areas, which can be done without significantly increasing the cost. It easily cuts blades due to vibration, but with patience, it will do the job you want. I replaced it with a better one (hundreds of euros) when I saw the capabilities that such a tool offers, and it has become the main tool in my workshop. Because many are torn between this and a ribbon, you should know that they are completely different tools.

It is definitely not suitable for professional use and it is impossible to cut straight!! There are much better saws with a slightly higher cost of around €20 more, which are worth much more even for an amateur...

Cutting straight, the blade turns by itself to the left, changing the cutting point. You cannot do precision work on straight cuts. This problem appeared from the first use, so I conclude that it is a problem of this brand or this specific model. It may be cheap, but if I knew that I wouldn't be able to do a basic cut, I wouldn't choose it.
