High-quality product, the price corresponds to the quality.

In my opinion, the price is totally justified for what you get!
Pros
1. The hours worked

4. Inexpensive replacement tips
5. Price
6. The superiority of the components and the product as a whole in terms of their quality

Cons

And the answer is no, he does not leave water stains on the floors.
