This is called business tactic and you cannot compare Banana to Apple.
All those products you mentioned are either people having problems with mostly to do with pH probe or equipment itself. Some you cannot even get reagents for.
All those products are 1 and 1 test only and they can't even keep the equipment in line and in check to work properly while trident is 3 in 1 test. There is no comparison.
No one said hold on and buy trident it's ones own decision.
There were prototype 4 yrs ago of 2 products that I wanted.
1 robosnail, an automatic glass cleaner.
They did release it but not for 1/2"or more glass thickness.
2 ReefBot, it was supposed to been in
market hasn't yet.
There are too many concepts that don't make it.
By the way alk monitor was also a prototype showed in macna by one man 3 or 4 years ago that one big company bought rights to and that became reality later.
By them showing off trident, maybe some Chinese company may come out with a similar device half the price and in half the time.
I am sure they are also aware of such.
