As a designer who enjoys DIY projects, I was looking for a reliable tool to help with my car maintenance, and this seemed like a good fit. The problem was my old speedometer was unreliable, especially on highways. This device solved that by providing precise speed data without much hassle. The setup was simple—just attach it and it started working, which was great for a beginner like me. However, it wasn't perfect; the initial location lock-in could be slow, and the engine readings weren't as instant as I'd hoped. Overall, it's a solid choice that does what it promises, but it has some minor quirks. My takeaway is that it's a helpful gadget for casual use, but might not satisfy someone needing top-notch performance all the time.
- Pros: The display is large and easy to read, even in bright light, which was a big plus for me. It felt very sturdy and handled bumps without any issues, so it seems built to last. I liked that it gave accurate speed readings without needing extra sensors, and setting it up was straightforward with the included parts.
- Cons: It sometimes took a while to find my location when I first turned it on, which was a bit frustrating. The engine monitoring feature didn't always respond quickly, making it feel a bit laggy at times. For the price, I expected it to be a bit more polished out of the box.
