Unsuitable for windows that are flat. It will not function on windows with double glazing.

This product works as expected. Consider the dimensions of your windows. It's very useful for areas that are difficult to reach. I suggest it; it's a helpful item.

The product is good and performs its intended function.

The package was shipped to Latvia and took a month to arrive. The item was well-packed in a makeshift Purry container. The main issue is the high delivery cost, as the device hasn't been tested yet.
