Review on 📚 Optimal Shop Portable Indicators: A Comprehensive Definition Guide by Bobby Martinez

Updated October 10, 2017 I downgraded this to one star. This is very unreliable. A cable that he thinks is good is actually good. Five other cables ranging in length from 1 meter to 30 meters have wires 13, 14, and 19 reported as open. The same break in five wires? I doubt it. All of these cables work perfectly. The last tested cable is really broken, but this gadget can't make up its mind. Pin 1 is open or not open (probably the wire has intermittent contact so this gadget reports correctly). Oh yes, a nit. Red letters on an orange background. It's really hard to read. First review: I haven't had it that long, but so far it's working great. The cable that gave me trouble is really bad. My problems are only related to the design. The on/off button is too easy to press even when it's in your pocket. It kills batteries. My other downside is that the removed part has to snap onto the main part. This can prevent it from being lost between uses.
