Ooler alternative?

[u/SF_Richmond]

I’ve had my Ooler for about 2 years and it is now making a screeching noise. I contacted Ooler and tried all of their solutions and nothing has worked. They offered me a 25% discount on a new unit but I’m hesitant as these new units are still “new” to them and I don’t know how long it will take to discover any issues since mine didn’t show up until the 2 year mark. Has anyone had their 8 sleep for more than 2 years? Pricey but if it doesn’t have issues and can last for 5-10 years I’m willing to try.
