Thank you for your answer ! As I ' ve mentioned I don ' t have any experience with timers or even pool pumps . I only have googlefu , and you guys . He told me , that the timer box is right outside of his bedroom , and they can ' t sleep because of the tickling noise the mechanic clock make . My first guess wast Intermatic PF 1102 T too , but he reaaly fast said NAY for it . Unfortunately he is not techsavvy , I will mention hi the aqualink option and your feedback over the noise level but I think at the end he will buy the PE 153 F . <| sep |> Honestly , for expedited , that ' s an awesome price . Only Prime stands out as being any better free 2 day , $ 3 . 99 one day . <| sep |> And that ' s the point if you want to almost spam social media with a good photo per day or couple days you must be a professional , who is always travelling for the landscapes and the great light . There are not many professional landscape photographers .
