ISV100w or ISV200w what is better?

Why is there two different models, what one is better?
Are there any real differences except the 200w doesn’t get as hot?

Hello,
The ISV-100W temperature control range is 77°F to 210°F (25ºC to 99ºC).
The ISV-200W temperature control range is 32°F to 194°F (0°C to 90°C), and it has added dry burn protection.
Other functions are basically the same.
