Which apex are you talking about? I don't recall exactly when in 2016 the current model was released, but it has only been about 4 years. I bought mine not long after release to replace a classic lite and it's been going strong ever since. I bought the classic lite around 2011, so got 5 years out of it before selling. Don't know if its is still running or not.
Curious what kinds of problems you are having? I did have some e4arly problems with the new version when it lost power. I now have it on it's own power supply connected to an UPS.
