Just got my first one (Copper HR) and this is totally my first experience with Hanna checkers.
What a horrible design! How have they been around for so long without basic updates / fixes? I design lots of items, nothing for consumers outside of 3D Printers but the design of these checkers is a joke!
Battery Lid - Has standard header pins connected to this... if you pull it out at an angle it can easily bend them. It also doesn't just come out easily, I had to use a small pick to pull it out.
Packets - Why are these not the width of the bottle mouths? How do you know you are really getting all the powder out?
Bottles - They are like the perfect width so that the tension of water can actually prevent water from coming out.
Lid - Half the time I think I need to press a button, the other half I just break it open. Works good enough, but I figure after a while
I mean it seems to work great, I assume I am getting all the reagent's out of the little packets, but it does seem to work fine... or maybe it's reading off. Hard to know for sure.
Just venting because I figured something this expensive and been in the market for this long should be better.
