Auctual user here,
Just got mine a week ago plus a day or two. I probably have a little different perspective than most as I build and maintain water treatment systems professionally. The trident is relatively cheap compared to the equipment I'm used to dealing with it's only $600 where a similar system I'd use for work would run a couple grand . When I opened the box to set up the first thing I did was disconnect the lines and blow air through everything, because when you store tiny lines like that in warm weather they stick together. When I did this I noticed one of the lines was kinked, reached in and straighten it.. to me this part was all common sense that I'd do for any equipment I was installing but I assume most people wouldn't think to do this and probably get some errors with lines clogged etc. From there I followed set up and everything worked as expected. The housing is cheap plastic, it's just a housing that holds all the components though so at 600 that's probably where they cut costs. All the little pumps seem like their accurate, I've tested a bit compared to my Hana alk, red sea ca an mg, and Hach ca mg. None of the tests are spot on compared to each other but nothing seems off, the trident is within a consistent margin of error when compared so that's what matters to me. The housing while on the cheap side does it's job holding everything in a small footprint, I wouldn't place it somewhere that it would get abused but generally don't put any of my equipment through unnecessary abuse.
