  • The best sprayer and the best price
Size: Inventor5
This sprayer is amazing. The battery lasts forever. I hardly have to charge it. The lid has a tight seal and doesn't leak even when filled to the top. Super easy to use and fantastic quality. This thing works great and appears to be made the same as my flowzone sprayer but at a fraction of the price! ... show more

  • Leaky lid seal
Size: Inventor7
Main seal on lid leaked every time I used it which ultimately led to it being returned.

  • Leaks which is a disappointment
Size: Inventor7
Leaks from the nozzle.. not good when used for pesticides. Spend the money and get a more reputable brand.
