### ⭐⭐⭐⭐ to not break old things
*by M***Y on 30 July 2024*

not bad but awkward to use.i have + old one from Tandy's it is great no batts needed to power it but the part that checks the button battery broke off or I wouldn't have needed a new one.u have to hold batts upside down to test + hold the negative lead to the bottom of the batt.but I think it will get easier in time so not bad + at least it tests about 13 batts.so quite good I'd say.
