### ⭐⭐⭐⭐⭐ Review
*by C***R on 8 July 2025*

I had the old white version that came out a few years ago that was fine but automatically turned off too soon which was annoying when testing multiple components. This one does turn off automatically as well but the delay must be much longer because I haven't witnessed it yet. The addition of the surface mount tester is nice and the internal battery lasts a long time. Very much worth the price
