I have not had any problems with these and was surprised to see others have had some defective bottles, has the one in the truck gets abused.

After I used it a few times the sprayer broke, the manufacturer spent to much time designing a fancy bottle instead of keeping it

I love the stylish convenient bottle with the built in cleaning cloth storage

The "purple" bottle and cloth 2 oz ScreenDx Cleaning kit from the same Digital Innovations company works great and I am a repeat purchaser of that one
