I struggle with pain and fatigue in my hands that can make it difficult to use household trigger-style spray bottles for cleaning products and misting plants and pet enclosures. All I really needed was something that would add a little bit of leverage and a slightly larger surface area to the original squeeze trigger.
This should slide on over the trigger on many, if not most, household spray bottles. The interior cavity tapers slightly to help it stay on without needing to be glued in place, but the extender can be removed easily to put it on a different bottle.
Having this has made things like mopping up after pet messes much easier for me. Hopefully you will also find it helpful!
