Not that actual brand but yes, I've had them and they are good in single glazed windows.
They help reduce condensation.
I dont think I would use them in double glazed joinery though

Years ago I was supervising for a company that built panel houses which were damn near hermetically sealed when closed up. After the first couple of houses those became standard a fitting in all rooms. They worked well.

Hmm if you are getting new windows just get h the latches that have a position where the window can be securely left slightly ajar
