Proceeds received by mistake instead of Metronic model I had ordered, but spontaneous and honest proposal for reimbursement by the seller if unsatisfied. So I tried using it to replace LNB dish and make a setting: this pointer has worked remarkably well and allowed a very precise timing both visual (needle) and sound! However, careful not to let the button positioned to a minimum (stop) on pain of having no signal and only then be able to make any adjustments (I had to turn my part about 1/4 turn before picking up a good signal). In conclusion, this article has given me full satisfaction and offers a quality / price ratio.
