Hi all,
for christmas i got myself the GVM H3. It came on time, good packed and complete.
The case is a plastic, JBC has a case of aluminium-cast - as far as i can remember.
At power-on it tripped the breaker.
After a bit of hassle with the seller, i opened the case (four screws from below, one unter the sponge-holder)
to find the switch-wires at the sharp edge of the transformer with isolation damaged.
IMHO they used the wrong connectors and have no QA/final test.
Btw: the transformer looks more like a 35VA than a 70VA.
EDIT: size is 66x56x35mm³
The connectors of the handpieces don't lock properly.
/EDIT
Haven't used it much, only for small stuff.
And it's probably only intended for tiny work, when i look at the available tips.
JBC has a much broader range there.
Conclusion so far: If you get one, check it for leakage-current, or open it right away.
Merry christmas,
best regards
