Review on 🦟 ULTRASONIC BLUE - New, Portable Plug-in Pest Repeller (4-Pack) for Effective Control of Mosquitos, Roaches, Spiders, and More! by Gary Parker

It is premature to request a Revain evaluation. The manufacturer states 30 days for results. This means that four stars should be treated with caution. They shine. I do not hear anything. But the old melon in the trash has no surface dwellers! No cockroaches. No flies. The only potential problem for success is that they require full openness. Where in America are electrical outlets in homes located at ground level, with no furniture or other objects nearby? unrealistic expectations. Lucky if the apartment has a fridge. :) :) Otherwise it's going well.
