I'm having problems with the FirstBuild app Please contact us here or call (866) 907-6718 with the version of operating system you currently have installed on your phone. For the schedule to run consistently, the device with the app should stay in Bluetooth range of the Opal Nugget Ice Maker. 2 Comments Date Votes -2 Allen Young February 20, 2018 03:48 Very expensive piece of junk 1 Michael Pines January 18, 2019 00:13 This ice maker is as reliable as any on the market. The great thing is there customer service and the technology built into the Opal. I had a issue with the lasers that tell the machine it’s full and can stop making ice and even though I was out of my one year warranty a supervisor gladly replaced it with a new one all I had to do was send back the broken one. Show me any of the other countertop ice maker companies that will do that. Great company Great ice maker.
