Vion Bluetooth Smart Digital Multimeter Connected to a Smartphone App Wireless Probe Automatic detection Automatic Measurement Automatic Diagnosis Voltage Tester Electrical Meter AC/DC Resistance Usb

I Immediately sent this back once I noticed how large the two probes were.I had purchased it to keep it in my pocket or bag as an on-the-go travel meter but unfortunately its too big to fit in a pocket comfortably. So instead I spent a little more and went with the pokitmeter, which does fit in my pocket.

I got this for my eight year old so he could use it with his bread board and electronic parts. It seems durable enough, but I have a few complaints:1) you need to remove a screw to expose the micro USB charging port. This is silly.2) The phone app is hard to use. It doesn't always pair with the probe, and it wants my son to create an account. I can't think of any reason why the app requires a login or location sharing. Again, this is silly.

Couldn't connect at all at first. My phone would find it but the app would not. After trying to figure it out, the issue lies with the acceptance of the location permission. After allowing the app to only track my location when the app is being used and allowing it storage access, the app connected and works.

I use it test battery packs I wish it was easyer to change

I could not reset the LOG FILE

This product works properly and well for its size. It is compact and it auto identifies what to measure. It also automatically reads out values for the user by connecting Bluetooth with a phone. The flashlight at the ends also provide visibility. Overall it is decent for its size and ease of use.

Good product does its job well

All in all I am very pleased with this product. It function just as it describes. I only wish it was a little smaller and had more attachments. Other then that I love it.
