  • โ€ขSprayer mechanism and wand frequently malfunction, causing frustration.
  • โ€ขRequires additional tools (spray bottle and funnel) to transfer liquid due to design issues.

Bottom Line

The Roundup 5375404 Weed and Grass Killer, 1 Gallon, appears to fall short of expectations for many users, who have found its effectiveness lacking compared to previous versions. The sprayer issues and need for additional tools for application further detract from its usability. If you're seeking a more reliable option with consistent weed-killing results, it may be worth considering other products or versions within the Roundup range known for their longer-lasting results, such as the Extended Control Roundup, which reviewers note as being more effective in total weed elimination.
