The unit functions well and has some very nice features. I waited awhile to post any feedback on this device until we had tried cooking several meals with it to get a good feeling of its overall functionality. 

It maintains precise temperatures and does a great job with everything we have cooked in it from steaks and roasts to chili and pasta dishes. We really like the precision temp controls rather than the usual high, med, low settings on most units. The temp probe feature is really nice for getting roasts to a good medium cooking temperatures and not over cooking meats.

Initially my first impression was that the control panel felt a bit flimsy but after using the unit more I have realised its just really touch sensitive and constructed rather well. Over all I like this unit and feel it is well worth the investment to add to any kitchen.
