(1) Adapt new UL 94V-0 Material, never adapt used material, some company adapt used material, for this, it is very easy, you just use fire to fire it, then smell, if it is smelly, this means the material is used material, another, to check the color of the products, used material color is dark and sometimes with black point on the products.

(2) inside contact is Copper painting silver, never adapt steel contact. We can really offer 50000times on/off. Steel type contact will burn easily, for this, customer can open the product and check, silver or steel. Steel contact will spark to get fire for your cabinet or enclosure, is very very dangerous.

(3) Another, for the terminal connector, we adapt is UL listed terminal connector, not normal type.

(4) Our thermostat temperature rising is 40 degree, not like some others,temperature is very high over than 70 degree, which will be dangerous for using, will reduce using life and will effect the temperature tolerance.

(5) The thickness of Natural’s bimetal is very thick, for this, you just open the thermostat to check inside parts, to compare every location, you will know the difference between ours and others.

(6) Temperature tolerance, right now, Natural adapt good quality material, so Natural’s thermostat has better temperature tolerance, for this, you can test ours and others.
