Top customer reviews
- Easy to use
- Battery lasts long
- Very easy to carry anywhere
- The sensors take a while to reach the actual measurement, it is not well suited to take very quick measurements
- The buttons protrude from the case, so they do get pressed while the instrument is in your pocket or with other things. It ends up turning on by itself easily (See picture).
