Arrives before Christmas 
You parked it, covered it, and want it mouse-free come spring. This 12V deterrent helps with that, using sound and light to make your RV or boat less inviting to critters looking for a winter home.
Whether you're parking an RV, boat, or lawn equipment for the off-season, this compact deterrent helps discourage mice and other small animals from getting too comfortable in your space and equipment. The MouseBlocker PROx is ideal for enclosed, low-light areas like RV and boat engine compartments, battery boxes, lawn and farm equipment, motorcycles, ATVs, and other 12V-powered gear. It's also a good fit for electric and hybrid vehicles with 12V battery access. Because you can use this with a battery maintainer, it's a great fit for the vehicle you use for your daily drives or vehicles, like tractors and mowers, you use once a week. If you know your vehicle is going to be in storage, unused for weeks or months, we recommend the plug-in version (MB34FR).
MouseBlocker PROx uses ultrasonic sound in an intermittent pattern and dual strobing LED lights to make dark, enclosed spaces less inviting, and performs best in spaces where sound and light can bounce off surrounding surfaces. You can choose from three output levels depending on how aggressive you want the deterrent to be. Because these sound levels are at a frequency humans can't hear, you won't notice a thing. The unit runs continuously, shifting between frequencies of 25 to 45kHz. This intermittant pattern helps keep mice from getting used to a single, constant frequency. It connects to a 12V battery, but only takes about as much power to run as an LED nightlight, and is smart enough to shut off automatically if voltage drops below 11V.
Works as described and arrived fairly f ast.
Works great! Highly recommend.
Easy to setup and use. Too soon to tell if it keeps the mice away.
So far so good, thinking about buying more. Haven't heard or seen a mouse since I bought one and I had a serious problem before.
This little device is simple to install. The combination of sound and light should do the trick to keep rodents out of the rig. This is much easier than using those smelly pouches, and you don't need to buy a new one every year.
Yes it works out great and going to be getting another one soon!
Looking for small, easy to hide device. These fit the bill!
