my first impression on unpacking the products is good ... not too bad for the price ... finished with a nice packaging (+ remote cable jack + spare fuse)
So I hasten to go I tried that ... branch ... and ... nothing ... zilch ... nay ... they do not light ... (since I bought 2 I tried with both)
so I think to remove the rubber tip preconceptions that prevents the camera getting to the bottom of the cigarette lighter ... and oh miracle it work (for one of the two only) ... I turn off the l unit ... then on again ... and nothing ....
I change the fuse and shoo it works again .... then I turn it off and then back on again and nothing again ... I give the other fuse (who I thought hs) but here it works again. ..the I turn then I turn back and nothing .... I change the fuse again ... and still nothing ....
I'll spare you the details of various and numerous trials with both devices, or I swapped fuses and tent thing with prolonged pressure etc ... (oh yes any record is delivered with these devices)
... Balance on both a market and has never worked in another 5 minutes ... So thanks to the quality of customer service amazon I have everything back in the carton printing the purchase back and shoo leadership position for the references of these products more than mediocre ... I ordered a more expensive of another brand we'll see ...
I can only recommended the purchase of this product ....
