I got the Opus when it first came out and had no freezing issues. The firmware certainly lacked many features, which they promised were coming and never delivered. My only real contact with their support was that my Opus screen ended up having some burst eInk capsules, but they were happy to replace it once I shipped it to them in France (gave an RMA right away and the turnaround was pretty quick). That replacement still works great (and is still lacking features). Bookeen, at least in the earlier days, has always had a big problem with making promises on firmware and not coming through.
