Does anyone else use HW Marinemix Reefer salt?

Im setting up a new tank, and another member on here recommended I try the HW Marinemix salt, due to the problems he has has with inconsistent batches of Red Sea Pro salt (what I told him I was thinking of switching to). I have been using regular Instant Ocean for years with no problems, but now that Im starting a new tank with a focus on LPS/SPS I wanted better levels for trace elements and calcium.

I know a lot of people really like using the Red Sea salt, but can anyone else weigh in on the HW Marinemix synthetic salt? Thanks.
