Don't use them! They are happy to take your money and it's all good as long as everything is fine. If you need any help you won't get it. The guy I spoke to at costumer service was a joke. It's a hardship to have anything changed and we made a mistake too. No way to get an extra panel,not even a colour code to match the unit. We were told to get a new unit. Plastic fittings and parts are flimsy. Cistern unit hardly fit. I went with their recommendation and had to cut the side of the panel so the toilet sits in the middle? Out of the 3 units it was the little middle part that was ok. I wish I ordered from someone else!
