We plugged it in and used it on the first day we got it and it works very well.  I love that it has a defrost and a broil option; which is great for when we are just feeding two and don't want to mess with a mess in the kitchen.  Recommend for sure!  

Pros: Plug and go, love the defrost and broil option.  Handy tool to have in the kitchen
Cons: None
