He did the job I wanted and more. I used it to cut some small trees that I had on my property with a diameter of ~8-10 cm. With a little care and good technique, it was not difficult at all. If it stops cutting, I will buy another one.

I used it to cut shrubs with trunks up to 5-7cm in diameter with a 3hp machine. Occasionally, it also hit rocks.
After 2 hours of continuous work, a few diamonds were left.
Considering the difficulty of the task, I would say it is value for money.
I have tried a Japanese wheel that costs three times the price and its lifespan was not much longer.

If you exclude the Japanese ones, which are unbeatable both in terms of quality and price (X7), this is one of the best on the market. I use it for cutting branches and it comes into contact with stones, so it lasts about 30-40 hours of work before the tips of the teeth "disappear" and then you throw it away.

The new ones I bought last 8-10 hours of heavy use, meaning cutting branches and cleaning around olive trees with frequent contact with stones.
If you want one for the day, plus fuel and your work, then we will have to reconsider it........!!!!!!
