Swift 500 Series cooktop/oven

I notice there are a number of disappointing archived posts on these stoves already.

We've just set off on our maiden voyage in a brand new van, only to find on the 2nd day that the oven runs nowhere near set temperature! After 2 hours of waiting, we had to set it at maximum to cook a vege bake and chicken fillets!

Today we discovered that the electric hotplate doesn't even get hot enough to boil water ... even on maximum!

Are most Swift stoves like this, or are we just lucky ...?

Cheers, Bob
