Unfortunately I ordered cartridges of one size and the ones they sent were a different size and description to the ones we normally had. It took several phone calls (and time) to sort the problem. I also forgot to order the 1/4 to 3/8 spigots which I then had to order and pay for. Although they sent me the larger brackets to install the bigger diameter cartridges to make them fit by the time everything was finished my mobile phone company notified me that the international rate calls to Dundalk to sort it had added 14.31 to my phone bill. As the cartridges and spigots had gone up considerably since my last order it was quite a costly deal!
