Melnor 65183AMZ Bluetooth Smart Hose Timer - 2-Zone Programmable Watering System with Quick Connect | Automatic Garden Irrigation for Lawns, Flower Beds & Potted Plants | Weatherproof Black & Yellow Design

The app is very easy yo use and intuitive.Plus, every Melnor bluetooth timer I've bought has lasted extreamly well. The first one I bought is 6 years old now. I store them in a small cabinet/shed thingy outside, and there they have survived yearly bouts of sub freezing weather (that destroys most of my hoses in the shed if I forget to take them into the house). In the warmer months when they are out in the garden, they are in full sun and rain and hail ... so far no problems. My only complaint is the Bluetooth power. They are used a bit away from the house, and I can only adjust the settings if I go outside. I'd prefer if they used wifi - I can easilly boost my house wifi to reach them - but I have enough of them that I'll only get wifi ones if I can be sure both my existing ones and any new ones will work with a single app. It's too much of a pain getting the timing sequences right if I have to switch back and forth between apps.I saw someone mention leakage - like I do on all pluming related screws, I use plumber's tape on the hose connection. I can't recall if I have replaced any rubber washers but I do check the ones on my hoses every year and replace any that get worn out, so I might have. I have never had any leakage.It did chew up the plastic screw threads on a cheap and poorly made pressure regulator for a drip line, but I'm pretty darn sure that was due to the pressure regulator being made of too-soft low quality plastic. (Unscrewing it to put it away for the winter damaged the threads - I wasn't holding it perfectly vertical so there was a bit of diagonal torque.)Overall a great product, if expensive.
