Yard Sentinel Outdoor Electronic Pest Animal Ultrasonic Repeller WEAT

This device is much more effective than many other devices. Has more control for settings. Much louder than others has a volume control Been using the Aspectek for 2 weeks. If it works well enough plan to use the 110 to 9 VDC adapter. Unit runs off of 4 C batteries. Rear cover is not snug enough to protect against warm weather. Nor does it come with any foam to protect the bottom entry hole for external power wire. A few tweaks and I think it just might work out.

New neighbor has cats that constantly live in my side yard and have turned it into their own personal littler box. Installed the HR131 (constant setting). Problem resolved. I installed it about 12" off the ground and left the audio setting low , so I can still slightly hear it. It's been about 2 months and so far everything is going well. The long AC adapter cord was particularly appreciated.

It works like a charm on my neighbors two unruly American Bulldogs! We've been dealing with these stupid, incredibly loud barking dogs for three years now! Since the owners won't do anything, we had to take matters into our own hands. After a bunch of research, I decided on this unit. The best part of this unit is that it plugs in so no need to check batteries AND it sounds (silently) EVERY time they bark. Every time! It has other features but this is the only one I'm interested in. They don't seem so interested in barking anymore. Hallelujah!! This has been the most peaceful 2 weeks we've had in a loooong time! Thank you "Bark Stop"!!! I may get another one for good measure :-)
