before i got this, i was constantly worrying about my aquarium's water levels, having to measure and top it off manually every other day—it was a real chore that took away from enjoying my fish. after installing it, things improved; it handles the refills automatically, which is a relief. however, it's not perfect; there are moments when it seems to overreact or underperform, causing small changes in the water level that i have to keep an eye on. as a perfectionist, i find that disappointing because i want something that just works flawlessly without any fuss. it's good, but not great, and for the price, i hoped for more reliability. overall, it's a helpful tool, but it falls short of being the set-and-forget solution i was hoping for. 😕
- Pros: it seemed intuitive to set up and worked well for keeping the water level steady in my tank, which saved me a lot of time and hassle compared to before when i had to check and refill manually every few days. the packaging was intact when it arrived, and it fit neatly without being obtrusive.
- Cons: it was too sensitive at times, leading to minor fluctuations that made me worry about consistency, and the build quality felt a bit flimsy for something i rely on daily. i expected better precision from a device like this.
