I am very pleased to finally get this product in stock, it looks like a very good smartcube, I have not personally tried previous smart cubes as they don't really interest me but that might change. It apparently features 280 hours of battery life but cannot be recharged (so the batteries must be replaced) and obviously has a much lower price than previous smart cubes!
