Avoid. Of the 4 toilets I have purchased with them, three became defective or altogether broken in less than 6 months of use. I may have been unlucky with the batch of products, but adding insult to injury, the customer service is terrible. I've been trying to have the defective items replaced for 4 months now. More than 30 emails have been exchanged so far (although many of them simply went unanswered). It's been weeks since I sent the pictures and videos of the defective items they have requested (a number of them!) but the technical team is still apparently incapable of - or unwilling to - reach a conclusion. I'll keep trying. And spreading the word. But if you still have the chance, go somewhere else
