First of all I have to say that I received the item on time and exactly as advertised on the website. I immediately used it to check one of my cars and it checked my battery as expected. I bought another tester, much larger and printable. So there was no difference in the result between the two, the device with printing capability is in the range of $40 more expensive compared to $11 for this device. You have to go to Auto Parts and get an outcome that may not be in your favor. The device is small enough to fit in a glove box. You can also perform routine battery checks, especially if you rarely drive your car. I will be buying 2 more to keep in each of my cars. I highly recommend this item.
