Have been using this wetsuit for the last couple of weeks in water around 16C (60F) with no complaints. Product description says it's good from 8-13 degrees C and Ill try that out this winter. Build quality is good. I've noticed chaffing/pilling where the velcro around the neck get stuck to the neoprene, but thats happened with every wetsuit I've ever owned. So far so good, may review it later down the road to see how it holds up after a year.
