Mouse Blocker Prox 12Volt High Powered Ultrasonic Mouse and Rodent Deterrent with with an Eviction Mode and Dual Strobing LEDs for Your Vehicle

After 3 days mice have moved out

Easy to install.Working well so far!

Actually works. I tried dryer sheets, big Vic’s traps, some peppermint rat spray etc but this thing actually works no damage since I did hook it up to a separate battery with a solar charger so I doesn’t drain my vehicle battery.

I have had issues with squirrels, mice, rats, you name it, chewing up the wiring on my vehicles. I purchased 1 Mouse Blocker Pro 12v to test out. No more damage, no paw prints in the dust, it appeared to be working, so I purchased a second Mouse Blocker Pro 12v, and installed it a few months ago. Those both came in the same packaging, which is what you see in the right side of the photo's I have attached.I bought a 3rd one about a week ago. The 3rd arrived, but on the box has Mouse Blocker ProX, the packaging is the same, except the the printing on the outside is different, and the printing on the actual device is different. The enclosed product installation and operation guide is the same as the previous 2.I installed the 3rd Mouse Blocker ProX, the documentation and description states the device shutoff when the vehicle is started, the voltage is low, and has the same install instructions. I installed it, and found there are some differences in the Mouse Blocker ProX, I had to do my own research and testing to figure out why the device I received didn't work like the previous 2. The manufacturer appears to have updated the device, or it is a new one, and does not operate like the previous 2 I purchased.Both turn on/off, have 3 levels of sound, and connect to the battery the same. The ProX however, does not shut off when the vehicle is started, and I noticed when I was installing it, if you move the ProX, it appeared to shutoff. At first I thought the unit I had was defective, but some testing I discovered if the device is moved, it shuts off, I had use a camera under the hood, start the vehicle, and start driving, it shut off, which explains why the device did not shutoff when I started the vehicle. I wonder how many are being returned due to the outdated documentation?If you purchase one, be aware there appear to be 2 models, the Mouse Blocker Pro, and the Mouse Blocker ProX. The documentation they send is for the Mouse Blocker Pro, not the ProX.The box on the ProX does not mention it shuts off if the voltage drops below 11.5v, and since it lacks documentation I am not sure if it does, or does not, I may wake up one day to a dead battery, ,which is when I will find out if it shuts off below 11.5v.The Mouse Blocker ProX does not shut off when the vehicle is started, I appears if the device detects movement, it shuts off. I am assuming this as it's my observation from watching it when I move the vehicle from point A to point B. It appears to start working again when the vehicle is no longer moving.I deducted a star due to the lack of documentation on the ProX, is it an update, a different version, they have different applications, like an electric vehicle, or can they be used on both combustion and electric vehicles? Only time will tell if it is as effective as the previous purchases.

Their 1 year warranty is uselessI have a mouse blocker (not the pro) that failed and no one from the company responded to my 2 requests and one phone call.

Last year, a rat infestation caused over a thousand dollars of damage in the engine compartment of one of our vehicles. What followed was an extensive trial and error period of oft-noted solutions involving peppermint oil, various spices, laundry drier sheets, cheap noise makers, etc., but the rats always came back. After much depression, discussion, and considerable research, we discovered the Mouse Blocker line of ultrasonic products, which, as we learned, is successfully used by ranchers and farmers, car dealerships and municipalities, and countless car enthusiasts, among others. So we purchased a 12v hard wired Pro model, had it professionally installed, learned how to use it, and shortly thereafter, a bit more than a week, the rats were no longer interested in that car!We now employ several Mouse Blocker Pro devices to protect our vehicles.Not long ago, the same model device, newly installed on another of our cars, began to fail pretty quickly. I called Matt Swift, the owner of Mouse Blocker, and he guided me through the process of testing and resetting the unit, after which we determined that the unit was dying. Matt very kindly, and quickly, sent out a replacement unit, which, after proper installation, works perfectly. Thank you, again, Matt!The Mouse Blocker Pro has alleviated a major headache in my life, and I highly recommend it. This product does not fall into the category of one of those crazy one-note high-pitched toys-- This a high-quality device that appears to do as it is intended, and it is supported by a company that understands what service means.
