Review on 🔴 Vaper 19419 Red Spot Spray – Non-Aerosol Sprayer (Red), 32 oz. by Adam Stone

They are much more economical than the smaller aluminum ones. The spray pattern is actually a mist and not adjustable. If you're expecting an adjustable nozzle, maybe someone will make one, but it's not. I fill it with Isopropyl Alcohol 995 for an insecticide safe for kitchen surfaces to keep them from freezing. Except that flies can bathe in this material. Use a soapy water sprayer to knock them off. The reason you need this is because alcohol over 50% disables the atomizer - it slides right around the plunger rendering it useless. It works great and lasts a long time on a single charge.
