“I found a recommendation for Harris spray bottles on the website 'everyday cheapskates'. They described them as the very highest quality available within a reasonable price range. I am very pleased because the bottles are as described: very well made, very reliable, and function perfectly. I would say EXTREMELY high quality performance (and extra features), especially for the reasonable cost. I bought the 360 Power Sprayer 3-pack, and I'm already recommending them to my friends. Thanks, you guys!”
Yes, every spray bottle the contains a straw will not spray upside down because there will be no liquid available to siphon from.
If you need something to spray at an inverted angle might be better to purchase a ready to use aerosol product that has the capabilities. We are more than happy to speak with you direct about maybe other options.
