I have owned an MJPTC200 thermal cycler for 6 months and have gone
through 4 alpha blocks. Each replacement block lasts a month or so before
drifting as much as 3C or having sensor failure. The latest replacement
did not even make it to me as our local service engineer tried testing it
before sending it on to me and it failed the tests.
I know of at least 2 others from 2 different countries with the same
problems with MJ machines. Not sure what's happening because the
PTC-100's used to work well. The PTC-200 is a great disappointment
and MJ has been very slow to respond to our complaints.
