Review on 🔌 Efficient and Easy-to-Use OBD II Connector Vehicle Memory Saver: Reliable 9V Battery Powered Solution by Stephen Thomas

This item worked great for saving all of my car's memory when changing the battery. I deducted a star because the wiring in my car was quite difficult. That's because the cable exits the side of the device, not the back. Because the shape of the OBD connector is not symmetrical, it only fits one way (i.e. it cannot be rotated 180 degrees). In my car, a 2013 Subaru Outback, there is a wall right next to the OBD port which makes it almost impossible to plug in this device as the output cable is on the same side. I ended up having to disconnect the OBD box in my car from the plastic wall it's in, then slide it behind that wall and connect this device from the back, which was difficult as it wasn't visible. A cable outlet on the back (as many other devices of this type seem to do) would make things MUCH easier and seems to work in almost all situations.
