    This review is about the number of required batteries: -

    It is the fourth meter I buy as I am a professional (two models from HILTI and one from LEICA, the DISTO 5). I have had this one for only two days and it seems quite good, and especially sturdy, while it fits comfortably in the pocket of my pants, which is very important for me. It has a variety of functions and compared to the DISTO that cost me about 600 euros, I can say that it only lacks the area of the trapezoid, the timer button, and the camera for measurements at long distances.
    However, for someone who does not need to take measurements over fifty meters, it is fine.
    Plus, it has Bluetooth and a rechargeable battery. The downsides are that it does not have a side measurement button and a spike for hard-to-reach areas. Otherwise, it is excellent.
