Orbit 24634 B-hyve XD 4-Port Smart Hose Watering Timer

I picked up two of these four port timers to set up irrigation in my backyard for over 40 trees. I live in Arizona so not only is irrigation important, but one day without can do serious damage to a young tree if something happens to the system. For the most part I have been very happy with these timers. I access them most often using the Bluetooth option from just inside my home. I do not have or use the hub, I don’t find it necessary.Here’s where their customer service comes into play. The only issue I’ve had with these timers is that they have occasionally frozen up. The one on my east faucet has frozen four times, the one on my west faucet has frozen once. When I say Frozen I mean stuck on the same screen, the timer is not activating when it’s programmed, I cannot connect to it with my phone via Bluetooth. After the first occurrence of this, which I didn’t notice for 3 days so my new row of fig trees took a major hit, I realized that I would be able to tell it was frozen because I could not connect via Bluetooth. If I slip the batteries out, wait 5 seconds then slip them back in the unit will work fine again for the most part. This was a real drag but it seemed like something I could work with since I have the Bluetooth application.The problem is that with Arizona’s 100° plus temperatures if it freezes up for the day then I have one zone on the east side that really gets hit hard because it’s all young rooted cuttings. While the rest of my yard looks fantastic, that one zone looks like it was just planted because it’s been hit by system freezes four times and keeps being set back. So I reached out to their customer service using the chat option on their website.Orbits customer service was fantastic! (To be clear, I reached out to the manufacturer not to Amazon.) The agent was very friendly and for the most part knew what I was saying. He continued to come back to questions about the app, like that was the cause of the problem, but I believe that’s because they have to ask a bunch of very specific questions before they can honor the warranty. I was on chat with them for about 20 minutes. I did not give them the model number because it was still in use and I didn’t want to take my system apart and read it from the bottom of the unit. This was not an issue. He just asked me to hop on Amazon and send them a screenshot of my purchase 4 months ago. Which was easy enough. I did not ask for a refund. I did not ask for a replacement. I was simply reaching out to them to let them know that there is an issue with their timers. Especially since I never let either of my timers get below 80% battery life. I’m pretty neurotic about that.After a pleasant 20 minute conversation with their customer service I ended the chat with a warranty code for the orbit websites so that I could go on and order two replacement units ( under warranty replacement ) at no charge to myself. No shipping charge, no cheap little hidden charges like that, just 2 valid replacements at no cost.This has been an overall positive experience and I wouldn’t hesitate to pick up their products again. As far as issues go, this is something I can work with if it happens on a new issues as long as I stay on top of checking everyday. Which is a little annoying but not the end of the world. I have otherwise had no issues. They’re constructed well and for the most part function great. Other than that one issue.(I did attach several pictures to show the difference between the zones. All of these were planted in May and they were all rooted cuttings that were about 8 in tall. The first two pictures are of fig bushes on the west side that have not had as many issues. They have multiple canes and stand close to 5ft tall already. The next two pictures of the smaller trees are from the zone that got hit from the timer freezing up. Obviously, they should be much bigger going into this time of year. They stand at about 1.5ft tall currently. But, I didn’t actually lose any and they should make up for lost time next spring.) [...]
