Catherine, you wont find any issues using ProfiLux it is trusted by some of the largest medical research centers in the USA, if its good enough for them......
Reliability is the key, nothing comes close IMO. Yes like anything advanced there is a learning curve but with a global support network on hand it is rare a question goes unanswered for long.
This is a professional system that just keeps on growing, if you want a controller that will last the test of time, then go with this as it will pay itself back in not a long period where other people are still struggling with flaky third party APPS and having to learn code etc.
