Hello, I ordered this charger following the various opinions, and its price is correct. Fast delivery, test result of the article in different cars with different receptors, the LED does not light, so HS. Back at the expense Amazon and sending another article in stride. (Back) The parcel was mailed back to the sender Amazon (problem mail) I take contact with the cat sav about 23:00! that checks the history and triggers another shipment. (Refunded if wish) service very courteous and EFFECTIVE. I finally get my charger that is functional, the blue LED lights. The screw-end of the spring contact can be easily unscrewed and you have access to the fuse of the unit. I put a drop of silicone on the threads to avoid losing the nozzle. I take off a star for the position that tends not to properly do its job and manhandle heavy packages.
