ReefKeeper - anyone still using it?

Hey SDReefs,
I'm back in the hobby after taking a long break. Just unpacked some old equipment and found an old ReefKeeper Lite with PC4 and SL module to control fan, heater and ATO. It was a basic setup that worked fine years ago. I plugged it in and everything seems be be working but I haven't really tried programming anything.
Now that the company is out of business, should I try to get it working or just invest in a Apex system or something else? I'm not really looking for anything fancy, just a simple system.
Anyone still using a ReefKeeper setup and if so, what is your experience with it?

Thanks in advance for any comments or suggestions.

I still use mine RKL when moving tanks or setting up temp tanks. Situations where I don’t need the whole apex.

Apex are much nicer if the $$ isn’t prohibitive. Great to have it accessible on my phone and to trend parameters like pH.

Thanks for your response PatientZero, just noticed you're in PQ as well.

Oh yeah! If you need anything to get started lmk.
