Hi Chris, thanks for the review.
We are sorry about the chipped dish and we can send you a replacement today.
Also please not that infrared thermometers are not accurate when measuring quartz and metallic surfaces. They reflect off the shiny surfaces and bounce the infrared beam away from the temperature gun.
The best measuring device would be a temperature probe with a k-type thermocouple (k-type has a wider range of temperature sensing than j-type does) so you can touch different parts of your nail and get an exact reading
The bowl temperature will be lower then the controller display temperature, but not by that much of a difference (you are definitely correct by saying the temperature of the enail is measured inside the coils thermocouple).
Thanks, have a great day!
