The shower can randomly heat up to 50 C without warning, which will burn you, then switch to summer mode and drop to 20C. I have been asking for a replacement or my money back but they just keep asking for videos and the same stupid questions. They have no intention of replacing this. This shower is faulty and dangerous. Victorian Plumbing are an absolute disgrace of a company. The worst I have ever dealt with. Other companies I have used are cheaper and give proper service. DO NOT USE VICTORIAN
