Rapidonline is part of Conrad Group, so in principle exact the same service and prices as from
www.conrad-electronic.co.uk.
Conrad is always having the same kind of support, meaning no support^^.
There are however 3 good things about Hantek DSOs labeled as Voltcraft :
1- they available locally in EU (well, that's for EU customers only), so in case of warraty easy and cheap to replace
2- Conrad got good prices from Hantek, so DSO-1062D from Voltcraft cost less than Hantek DSO5062B from China
directly (and DSO1062D=DSO5062B),
3- one can buy 4yrs warranty for few $$$ only (totally then equal to china-import + tax price!).
The P series and other models are however not available at Conrad, so no compare to other sources.
