Arrived promptly although after installation I have not noticed much difference. 700 mile trip with my RV , mileage is still 10.1 response is the same still unsure if it was a smart purchase, hope 180 day trial is still valid. It’s still installed and I have more miles to go, so will know in another week or so how the mileage is.
