Ordered it to try and eliminate squirrels from returning to attic. When installed, they immediately left and have not returned. [...] Sure seems to be working. Since the attic is pretty large, I ordered a 2nd one to place at the other end as additional protection.

This item really works! We have an old house with a cellar and a crawlspace under a portion of it. A possum got in the crawl space (that’s another story!) and into the cellar. We had also had skunks under the porch adjacent to the crawl space, and no we don’t live in the country. We purchased this, plugged it in and the skunks are gone and the possum’s relatives have not returned!

Excellent Product. Top Notch! I purchased two of these machines last year and have moved them from place to place to help with many different problems.

This year we are working on Mosquitoes, flies, etc.

Today I am purchasing 2 more unites [sic]. One for my bedroom and one for the front porch.
We have them in the dog kennels and no more mice hurray.
Mice no longer get into my clothing, and spiders are a thing of the past.

We have tried other products and this is the best one for the home that we have found so far.

I bought a TX-PRO about a year ago. I’d acquired a little sports car over the summer and had cleaned out a detached garage to accommodate it. Friends and neighbors mentioned the damage that squirrels and mice had done to stored cars and motorcycles over past winters. I sat the unit on a table near an outlet, on the driver’s side of the car. It’s been running ever since. I change the frequency and volume every now and then. No damage or nests of any kind have been found. The entire garage remains in pristine condition. Pests of all kinds have found other places to live.

I bought second unit a couple of weeks ago. I’d heard gnawing sounds coming from under a staircase one chilly afternoon. A quick inspection of the nearest outside wall revealed missing pieces of grout between the basement door sill and the foundation – large enough for a field mouse. Initially, I pulled the first TX-PRO from the garage and set it up on the stairs to chase the mouse before making repairs. It worked! I decided to order a second unit as a spare for the garage, but then put it to work full-time in the basement after it arrived.

The TX-PRO is effective.

I bought the transonic pro due to mice and rat infestations in my home. I haven’t seen or heard any mice in my home since the day I plugged the transonic pro into my wall outlet. I heard a mouse scrambling to exit my premises shortly after I plugged in the Transonic Pro. I haven’t heard any mice or rats crawling in my walls or ceilings. This product Works!
