Amazing! We use the panini grill plates almost every day with wraps and it is great. 
Use to clean because the plates are removable so you can wash them properly in the sink.
Heats up quickly and it's size means it doesn't take up too much space. We've used the sandwich maker as well and can't wait to use the waffle maker plates as well. A great little toaster!
Would recommend to anyone looking to buy and having the 3 in 1 option made much more sense than just buying 1 specific toaster.
