### ⭐⭐⭐⭐ WILL LOCATE STUDS FOR SURE, ONCE YOU FIGURE OUT HOW TO USE IT
*by J***T on November 26, 2025*

Instructions are very hard to follow, and may not be completely accurate for the model i received, since they were evidently originally written in Chinese, and poorly translated to English. I finally figured it out for the most part, and i will say the thing is sensitive, locating studs fairly accurately. As for locating metal and wires, I'm not so sure. I would prefer that it just used regular disposable batteries, rather than using a provided USB-A to C connector charger cable. The carry case is nice, but as far as I'm concerned they could do without it. The beeper signal is extremely shrill to the point of being annoying... supposedly that can be turned off.
