Finally, my UTi260B has arrived! (from China and not Europe, as i had ordered it from...). It has been a very long time since i received a full refund and i am lucky that i did so. I will explain.
The unit is a very nice piece of equipment for home users and it is value for money. The resolution is nice and you do not have to use the optical image at all (but is saves an optical image as well as the thermal when you press the trigger). It is precise, fast and does almost everything a home user would ask. The price is also fair for what you get. If you are a professional and would like more features and precise calibrated measurements you can get a Flir for three times the money. But for the average non-pro user it is perfect!
BUT: After a couple of days mine also developed a hot spot at the bottom!! I remember someone here mentioned that he had a hotspot too and people replied that it could be due to dust in the sensor. Well, maybe it is not... Mine is OK when it starts up cold, but develops the hotspot as it warms up!
It does not matter if i move it around or not. Hotspot always appears. Sometimes it might be a cold spot. So, i believe that it is a deficiency in some sensors, or improper factory testing, and it is the risk you take for such a low price.
However, i suggest that potential buyers test their meter for a few days before declaring it 'received' and miss the refund, if something like this appears.
Other than that it performs perfectly nice. Clicking (and pausing for half a second) for calibration is done frequently when it starts up, but gradually becomes rare when temperature inside the unit is stabilized. I am very happy with the overall performance and user experience. But i am happy i got a refund because now it is way too late to fill in any claim from the seller.
