    Good product for intended use. wrote

    I bought this sprayer because it was one of the models that the 4 - 8 ft. telescopic wand fits. I needed extra reach to spray the soffit and gable ends of our house for Asian lady beetles and stink bugs and the slope around our house makes working at height from a ladder treacherous. The sprayer is rugged and easy to use although it is a little difficult to get completely drained and dried out for winter storage.
