It actually works!!

This meter was very easy to use and was pretty accurate. The "test" solution, which was supposed to be 4.01 ph, came in at 4.06 ph when I used the meter. I also tested Essentia water which touts a 9.5+ ph level and it came back 10.0 ph. So if you're wondering Essentia water is the REAL deal.

Very pleased!

We heard rats in the shallow attic of our 600 sq foot single story rental. The rats were eating the bark off of our Mimosa tree, just outside the rental. I sprayed the tree with rodent spray, and placed this device inside the rental. No more rats!! I am as pleased as I am surprised that it worked so well. It doesn't emit any sound that I can hear, and didn't raise the electricity bill at all.

I am so glad!

Bought this as we had a problem with ants coming into the house from the back garden. We had tried a number of traps and bait etc but they still kept appearing! Tried this as a last resort and so far we've not had a problem with any more ants in the house! it also got rid of mice. I am so glad I found this .

These absolutely work.

We had rats and roaches in our shed..we bombed roaches and installed these...this got unplugged and rats returned..plugged back in and they are gone..since we put this in our house no sign of roaches..

pefect work

I have been using this product for two weeks, I was suffering from ant's, I didn't see as much as I used to see, but I have big house I might need one for each room it's summer now and I don't want to see other pests.

Recommend!

I've had this on for a couple of weeks now and I haven't seen many beasties, if any, in that time. I had been getting bothered with slaters and spiders in my kitchen. I don't want to jinx it but it may also work on slugs, although I'm not sure if they have ears. I've only had one in my kitchen since I put it on. Could just be the time of year though.

Would order again.

Great product, fast delivery.

Not bad!!!

Arrived super fast and was exactly what i expected
