  1. Just picked up an Innova 3040e from Amazon. Works great, it’s simple, updated the firmware when plugged into the computer. Everything has gone smoothly with no error. The only error so far is my damn car. Mine did not include a pouch nor a mini USB cable, but If you are looking to buy this particular model, save yourself $20 and get it on Amazon. I will recommend this tool and the Innova brand. Good quality +1
