It is worth more than its price. Very good quality materials. Practical. All Karcher products with the pressure being adjusted with the yellow switch that moves up and down require attention.
Because it is a plastic (quality) construction, one should not let it slip from their hand and fall to the ground. One of the two connections of the water pressure adjustment switch can break.
I have experienced this due to my own fault. The water gun continues to function.
Do not let the water gun fall to the ground from your hand. Hold it yourself.
This is not a Karcher issue. In all plastic water guns, caution is required due to the fact that the construction is plastic.
The solution is to purchase a metal water gun, but its price is double and it is heavier.

Very good. For those who need its three functions, it is by far the best quality product I have ever held in my hands. Additionally, it has flow control, and contrary to all my previous experiences, it works very well here.
