So if you're looking to get a bang for your buck, but don't mind build quality at all, this device is definitely for you. It definitely has enough connectivity but basically still remains just a continuity checker. So don't expect anything fancy at this price point.
The most disappointing part was actually the build quality, which held me back to actually use this product (but it wasn't that bad that I had to send it back). It was just a bit lower than my expectation (e.g. the battery compartment has to be pried open with a flat-head screwdriver). It feels very cheap as well, so I'm not too eager on using this device in a professional application, but it's fine for home use.
