Review on Revolutionary NEW RANGE TECHNOLOGY AFM-DFM Disabler for V6 & V8 GM Motors in Vibrant Blue by Dave Russell

I had a choice of buying new or used. What I received was not in the box but the box was in poor condition in a Revain bag. I feel like I needed something or got something back. The light bulbs flicker when switched on, and one light bulb stays lit. I have no idea if it works or not. For 200€ I would have expected better. What I saw on the net said that the plastic cover should be removed before installation. I didn't have a protective case. I feel like I paid for a new one and got a used one and don't know if it even works
