Haibinsh Solar Mole Snake Repeller, [New 2019 Upgraded] Ultrasonic Animal Repellent Vibrating Rodent Repellent Sonic Wave Pest Repeller Gopher Repeller Vole Chaser Pest Deterrent

i've added this device to my arsenal of critter deterrence. the feature of vibration is a nice add.i was hoping to capture this device in action with my motion sensing camera - but I haven't been able to in recent weeks - because i am not getting any critter motions!i am still getting critters in other areas of the backyard, as they just find new ways to get in. But for this particular entrance guarded by the device, it's been quiet. the combo of vibration, strobe lights, and ultrasonic pitch is unpleasant, and i think the animals remember that. So placement of the device(s) is important in order to guard easy entrances. Angle of motion sensor is also key as smaller critters may get through if the sensor is not slightly pointed down. It takes some trial and error and tweaking in the dynamic outdoors environment, but overall effective when you get it right.

Great part thats you can control volume and different settings working well from solar larger size and better usage more longer distance of control. Nice dark green color looking organic and great durau plastic

It did not work
