Brand new trailer. We were not going to let this happen to a brand new trailer. Put four units in before the first storage season — didn't even wait to find damage first. Came back in April and it was exactly as we'd left it. We'll never know what would have happened without them. We don't want to know. That's the point.

Twenty-two years of RVing and I've written off more damaged items than I want to calculate. Mattresses, clothing, a slide motor, three separate wiring repairs. Accepted it as the cost of ownership. A friend explained the habituation mechanism to me — how every deterrent I'd ever tried was a fixed stimulus the mice learned to ignore within two to three weeks. Put these in before last storage season. Most boring spring opening I've ever had. Completely clean. Boring never felt so good.

Solo woman, full-timer, two cats. The cats don't catch everything and I won't use poison with them in the rig. Found a nest in the cabinet under the kitchen sink in October — not even during storage, just parked for a week near a field. Put these in immediately. Four months later, zero evidence. The cats still patrol but they haven't found anything to patrol for.

The peppermint oil was working. Then it wasn't. The snap traps caught three mice. Then they stopped catching anything. The Fresh Cab sachets smelled great for about a month. Then apparently the mice just stopped caring. Bought these after reading why everything I tried was guaranteed to fail eventually. First spring with nothing to clean up. Nothing.

We had eleven events across our lot last winter — neighbors reporting damage, two of them considering leaving our storage facility. Switched the whole operation to variable frequency coverage in November. Zero events this spring across 40 units. My customers are noticing. I'm recommending this to every owner who drops off.

Single mom, two kids, full disclosure. The idea of poison anywhere near where my kids sleep was never happening. Tried every natural option for two years and watched them all stop working. This doesn't use poison, doesn't use chemicals, and doesn't stop working in two weeks because it never gives the mice something stable to adapt to. We opened the rig in April and my daughter immediately started arguing with her brother about which bunk was hers. She had no idea what that moment meant to me.

Managed RV storage for fifteen years. Watched owners come back to damage spring after spring despite spending real money on deterrents. Started recommending these to my customers eighteen months ago after seeing the research on variable frequency. Of the owners who covered all three zones, none came back with damage this season. None. First time in fifteen years I can say that.

Our insurance doesn't cover rodent damage. Found that out the hard way after a $3,200 fuel line repair. That's $3,200 out of pocket for damage I thought I'd prevented with dryer sheets and a plug-in ultrasonic I'd been running for three years. These units run on a completely different principle and the difference shows. Not a penny spent on repairs this season.

I'm a high school science teacher. I teach habituation to sophomores every fall and never once connected it to why my RV deterrents kept failing. When I read the explanation — fixed stimuli get classified as background by the rodent nervous system within weeks — I felt genuinely embarrassed. Put four of these in. First clean spring in four years. Should have figured this out in year one.

My husband has what I call his November face — this distracted look he gets when the RV goes into storage and he starts worrying about what's happening out there. He's been making excuses to drive out to the lot and check on it for years. This winter he didn't go once. We opened it in April. Clean. His November face is gone. I didn't expect a rodent repeller to fix that but here we are.

Spent four years putting moth balls, steel wool, and every deterrent I could find into this trailer. Found mouse turds every single spring. A retired pest control guy told me I was wasting my time with anything that didn't vary — that mice habituate to constant stimuli within days. Tried these. Fifth spring opening — nothing. That's not a coincidence.

We winter in Florida and store our coach in Michigan for the summer. Five months unattended. We'd had two seasons of damage — nesting in the engine bay both times, one time in the slide motor housing. These covered all zones including the engine compartment on the 12V adapter. Came back in September to a clean rig for the first time in three years. The storage facility operator was surprised. We weren't anymore.

Came back to our trailer in spring to find droppings on my pillow. On my pillow. I don't have words for how violating that felt. Put four of these in before last fall. Opened the bedroom in April and sat on the bed for a minute just appreciating that it was exactly as I'd left it. My husband thought I was being dramatic. He wasn't there the year before.

Skeptical of anything marketed as ultrasonic after two different devices did absolutely nothing. Read about the variable frequency difference — how fixed frequency habituates within two weeks but variable keeps the loop open — and it made enough sense that I tried it. Two storage seasons, zero damage. Still somewhat amazed.

I live in this thing full time. Poison is not an option. Traps are not an option when you're moving every few weeks. This just plugs in and runs. Been using it for seven months. Not a single dropping inside. Not one. First time I've felt like I actually solved this instead of just managing it.

The wiring repair was $1,400. That's what it took before I started taking this seriously. Put these in before last storage season. Came back in March and the electrician who did the original repair came with me to check his work — his idea, not mine. Zero new gnaw marks. He's recommending these to all his other RV clients now.

We have two dogs and absolutely cannot use poison in the rig. Tried every natural solution out there — peppermint, cedar, dryer sheets, Fresh Cab — and watched all of them stop working within a few weeks. This is the first thing that doesn't rely on a smell that mice eventually ignore. Clean rig this spring. Dogs are fine. Family is happy.

I've been RVing for 30 years and accepted rodent damage as part of the deal. My neighbor told me about habituation — how everything I'd been using stopped working after two weeks because the mice's brains just filed it under background noise. Made sense immediately. Ordered the 4-pack, covered all three zones, and this spring was the cleanest opening I've had in a decade. Wish I'd known this 15 years ago.

My husband and I lost a mattress last winter to a mouse nest. Not replacing another one. We put these in before we locked up in October and I checked in February for the first time without dreading what I'd find. Clean cabinet under the sink. Nothing on the sofa. I actually cried a little. Worth every penny.

Third year of putting this rig away for winter and the first year I didn't come back to a mess. Put four units in before storage season — one in each zone like they say — and opened it up in April to nothing. Not a dropping. Not a smell. I've spent probably $300 on Irish Spring and peppermint oil over the years and this is the first thing that actually held for the whole season.
