I have BT-75EU.
It is made of good materials, feels really solid and high quality.
Display fonts are a bit weird, but quite visible anyways. Back light is very good, but a bit short.
Common ground probe is detachable, cable used is high quality silicon, but a bit thin and very flexible. I expected a bit thicker cable. Don't know if it is going to be a problem, so far so good.
It has vibration alert when probing high voltage, built in LED lamp, non contact voltage detection...
I checked voltage (AC and DC) and resistance accuracy and it seems to be well in spec.
All in all, like other Brymen stuff, full of functions, good quality and fantastic value for money. If I have a suggestion, a thicker, more rugged black (ground) probe cable would be more appropriate.
If you have a more specific question, ask.
Regards,
Sinisa
