You can't give this machine a bad rating. This Hamilton Beach Panini Press does one thing and one thing only, but it does it very well. If you enjoy pressed/grilled sandwhiches you will love this machine. As I write this I'm eating a feta/olive/artichoke/roasted peppers on pita sandwhich hot off the panini press, and it's scrumptious. I actually bought this as a christmas gift for my mother, but I probably use it more than she does.
The machine looks good on the counter, and has a large, non stick service. It's not on a hinge so it's designed to accept even the thickest sandwhiches without squeezing all the filling out. You can even "lock" the lid down to apply constant pressure, or lock it up to maintain minimal pressure or to not make contact with the top at all. It's great for quesidillas as well. Ignore the user that says it takes too long to heat up, it takes only a couple of minutes, about the time a waffle maker would take to heat. Even cooking on the stove you need to take a few mins to heat the pan! Also ignore the comment that this machine burns the bread before heating the filling, I've never had such problems, although I do wish there was a temperature control for further versatility. But my bread never burns... I find 2-6 min will brown the bread perfectly, from lightly browned to nice and crispy (depending on how you like it) without burning it at all. I've never burned anything on this machine. Maybe this would happen if you used the wrong bread, but I can't say for sure. I even once used it to grill some chicken, and it did the job nicely, though it's not really designed for that.
There are a few down sides. This is a no-frills unit. There is no included recipe book, just a few hastily thrown together ideas in the instruction booklet. That's not a big deal, as I'm sure you'll have plenty of ideas of your own. More disappointing is the lack of a temperature control. That might have helped the reviewer who had problems with bread burning, and would give better flexibility. The machine itself gets very hot on the outside, but that's to be expected. Keep youngin's away from this thing, though. There's no alternate "plates" or cooking surfaces for say a flat "griddle" style surfaces, so if you prefer that or find a need for one. I don't think that's a huge deal, but I do think I'd prefer a flat surface, as that means more surface contact and more browning (though you wouldn't get those nice brown grill marks).
This is a decent machine at a decent price. It could be better with a temp control, some added weight, and some extra features, but all-in-all, you can't complain too much there.
*Update*
After having this a while, we noticed the non-stick coating was beginning to a) lose its nonstick ability, and b) peel and flake off the cooking surface (and into our food!).
This was within a year or two of owning and using with only non-metal utensils. We only used the grill occasionally, so it's not like it was due to over use.
I've also since come to realize that nonstick in general, and PTFE (Teflon) in particular, make absolutely no sense in an application like this--the surface must get quite hot to do it's job well, and that both burns the coating and causes it to release harmful fumes into the air. I've reverted to using a pair of well-seasoned, cast-iron pans, one small enough to fit inside the other. I preheat the pans until they are very hot, and let time and weight to the rest. No harmful fumes, no limited lifetime, and cast iron holds and distributes heat as well if not better than even the higher end presses.
If you're looking for this kind of grill, you'll have these problems with almost any model, but I would recommend a plain cast iron model without nonstick if you can find one (I've never seen one). You may also want to just try doing it the old fashioned way. Honestly, I don't remember why I thought having a dedicated sandwich press was a good idea.
