It was so hard to find a zero pressure timer. This one works great for my rain barrel.Very easy to use and an excellent zero gravity water dispenser. Only issue is that one of the knobs on this timer (the time setting) keeps popping off. Besides that it works very well.I had a purchase from this seller before and their product was great. I decided to return for this new model. I have been testing and using this one for about two weeks and so far so good. The setup and installation were easy and intuitive - no issue or leak. Tried different settings and all works well. I had used this to replace an older timer for my backyard. The LCD screen is easy to read and navigate when setting up the programs. Tested the rain delay function one day and did work well. Definitely will be a return to this seller for other products when needed.I had two timers with led screens and both went bad, after a while in the sun the screens went blank, so i ordered this type with no screen, and I think it is going to work, only had it for a few months and so far so good.Excellent Quality product , Fast delivery , Highly recommended .I like it because it's small enought that will fit right .BUT it only last 1 year and now it's stop working. I took it out during winter time .This was used on a water tank to water plants. It works great without much water pressure. A little different to set up but read the directions and it will be easy.I installed the batteries and it was up and running in literally less than 5 minutes. No digital timing to try to understand. Just turn the dials to the frequency, how often, and tighten it to the hose & faucet, and done! I've had it plugged in set to run every 24 hours for two months and it hasn't failed once. If I want it to run every 48 hours instead, it's just one click of the super easy to read dial. Doesn't drip or leak at all. I will definitely buy this again when I need it for another hose hookup.Works perfectly, easy to use and very easy set up.
