Water Level Controller

i got this because my aquarium was losing water too fast from evaporation, and i needed a hands-off solution to keep things stable for my fish. it works okay, but not perfectly; it's saved me some time, but i still find myself double-checking it, which defeats the purpose a bit. as a researcher, i expected better accuracy and build quality. overall, it's an average gadget—does the job but could be improved. :)
- Pros: it does what it says by topping up the water when it gets low, which saves me from constantly checking and worrying about my fish. the setup was easy enough that i managed it quickly, and it's small so it doesn't clutter my tank.
- Cons: for the money, it feels a bit flimsy and the sensitivity adjustment is too finicky—i had to fiddle with it a lot to get it just right, and even then it sometimes misses the mark. from what i feel, it's not as reliable as i hoped, which is disappointing.
