Make sure it fits.
Sturdy build and easy use, I am using it in one of my cars, unfortunately I can't use it in my Z4 because the battery is in the trunk and it doesn't have the clearance for it. This makes winter storage easy

Nice switch, might not work with your battery cable.
This is a nice quality switch. The difference between it and most others that look like this is that it has notches in the case that provide a little extra clearance for the battery terminals. The bad news is that the output terminal is smaller than the US standard, so if your battery cable terminal is the old-fashioned kind with a limited amount of tightening, it won't work.

Make sure it will fit in the given area of your car
Probably works great, but won't fit in the battery space on a '98 Volvo. Additionally, when trying to return it, a free return requires me to go to an official UPS store which, in myh case, the nearest is 50 miles away. Hardly worth the trip.

Solid feeling, good quality.
Feels like quality. Red knob is very secure, and rotates 90 degrees to Off when needed. I have a car driven only a few times per year, and this switch helps prevent battery drain when the vehicle is in storage.

Works as described
I have a truck that doesnโt get driven often and so far this has kept the battery from going dead from just sitting. Works as described.
