yes they sent a spare spring with the aqua dapter when it came as i believe its a known fault. I asked for a couple more spares when i used that and they arrived within 48 hours free of charge. I cannot fault them and really like the product, But I put my last spring in on wednesday, so i will have to see if they will send me some more. They were supposed to be getting new AD's fitted with heavier duty springs, and the springs were supposed to be available on their website, But when i looked i could not see any.
