I have the GHL controller. I’ll be completely honest with you... you need a lot of time and patience to figure everything out. It seems to be a really well made product, though. The jury is still out for me on their customer service & support. With all that said, I’ve committed to GHL as a system moving forward. I would recommend it.

Love mine :) Well built, no issues to report. Took a bit of getting use to the programming language after switching over to it, but have had no issues with mine and would not choose any other controller.

Don't want to hijack this thread, but which probes do you keep in overflow and why not all in sump?
