Not noticed it being mentioned.
From the spec though:
Plus points
No battery
No visual overlay to mess things up
Temperature measuring
Cheap for new
Vastly better than nothing
Minus points
Fixed focus *
Low pixel count
Is 'available in several colours' a red flag on allegedly 'professional' kit?
As for temperature, not as much of a concern as you'd think. In fault finding you would not let the faulty part get to 120°C. A quick blip of power is often enough to see overheating parts 'light up', before magic smoke time.
For hotter things it may be more of a problem, much depends on what happens to the picture over 120°C, even if the readout caps.
* You would need a secondary lens, or you'd be dealing with 'spot the hot fuzzy blob'. Plenty on those here, mainly to fit on handheld cameras though.
Might be able to take it apart and refocus it to suit 'PCB only'
To note
50° field is pretty wide - that is fire camera spec. OK for PCB but not ideal for the other uses they suggest. Consider how big each pixel becomes at a given distance.
You of course need the phone attached. Remoteing the head is not always easy - several threads on that here.
What other options depends on whether you want a 'phone attach', whether you want 'normal' as well as PCB use, is EUR140 the budget, do you want a project or 'open box & go'.
