"Well on the Aquatube side of things I was really impressed, the overall build quality on both items was superb. Then add to that they both actually done the task they were meant for really well and both devices are winners in my book. The Aquatube is the ideal refill point, although I still cant help thinking they could of included a real life size template for the product in the box. This would have made this package perfect for me. Having said that I don't quite remember the last time I felt so relaxed about filling and draining a system"
