Red SeaReefLED 90 Watt Saltwater Aquarium Light Reef | ReefBeat App Controlled for Fish Tank LED Lights for Corals Reef Marine

This is not my first Red Sea LED90 light. I've had two in use for a few years for my coral tank. The original two were set up by a professional, and even he couldn’t install them on the first try and had to returned & exchange the entire set before they were successfully installed. I bought this one to replace one of the two that went bad. I didn't expect adding this light to my existing tank system to be so difficult. Installing the light was simple, but it took me several hours and dozens of failed attempts to finally connect it to my app. The app provides detailed instructions, so there's no confusion there. I feel the problem lies in the weak and unstable signal of this light, which caused the numerous failed attempts to add it to my grouped system. Concerned that the issue might be with my setup or home Wi-Fi, I restarted my entire network, uninstalled and reinstalled the app, and still encountered the same failure at the same step. The most ridiculous part is that after spending several hours and failing countless times using the same steps, it finally connected successfully. I felt like I had won the lottery. For such a simple device to waste so much time before it can be used, I can only say that the quality of this device is very poor. If you don't mind wasting as much time as I did, you can consider buying it; otherwise, I would recommend purchasing a product with more stable quality and simpler operation.
