Yes, I have. I caught a post via one of the automation threads here or somewhere else and started to read up on it. I have nothing against it really and it seems like a unique way of doing tests. However, the subscription cost is a bit high for me. Before we go down the reagent vs. disc subscription vs. other options I believe I understand both sides of the story. I believe the hobbyist will have to choose which one works better and make a choice if/when they are ready.
If the Mindstream offered a different subscription fee I would probably consider it. Think NetFlix for example. DvD, 4K, how many discs out, etc. All at different prices. Most people with controllers be it GHL, Apex, or say Reef Angel, already have temp, pH, ORP, and salinity covered. So to me it would sort of make sense to offer, if possible, a disc with fewer test metrics and be done. I heard earlier today that the thought why they can't is because some of the tests are used to compose or reference other tests. Makes sense. So back to 10 tests all or nothing for the going subscription rate.
I personally have no issue with the method but it just isn't going to work in my budget and a 2 month reagent or 6 month package may work better. Yes, there is maintenance (DIY cheaper, send in cost more) every 18 or so months so we need to factor that in. MS is unknown at this point in time.
Like I said - I think the results may be better than the reagents and as more units of both come online the hobbyist will get a better understanding. Then there are some others due out so who knows. Thus the longer we wait for Trident the more it allows other options to come out with data to compare. So yeah - sorry about TL;DR wall of text.
I've heard and read about it. The subscription is tough for me at the moment (2 in college). Maybe if they give military discount
