hi there
have used the product a for a couple of systems stopped using them after a fallout over a faulty unit. found the service team is not the best.
They have another system under a Coel badge and when that when faulty i had to deal with the manufactures in italy as ACH wouldnt get involved in the end it was replaced for a gibidi
Now use faac and will not go back in my opion the extra cost is worth it.
