Question: Does this unit heat bottom and top equally well?
Document: I also liked how easy it was to clean the plates and how well it cooked my food, once I got used to the temps and timing. So for these reasons, I would love to give it a 4 star rating. However, one day,I was cleaning my counter when I lifted it and noticed that the coils inside had burned straight through the bottom of the unit and began burning my counter top (turning my light colored counter brown)!!! The coils were exposed, and it was obvious there was electrical fire damage to the unit underneath.
Delivery:Several reviewers on Amazon.com noted that their grills were delivered and the top was cracked. They were not happy. But I figured that Amazon.com is shipping out SO many of these that occasionally one is damaged. Well, I found out WHY the units were getting damaged. Mine was too when it arrived. Amazon.com ships (or used to ship...not sure if they still do) the unit in the original packaging and it's not enough to protect the unit. They were EXCELLENT about replacing it, though, and the next unit was packed correctly in a second box with plenty of packing material to protect it.Here's the Bottom Line, first:Well, we are EXTREMELY disappointed with this grill.
I'm sad because I used my G. F. grill a LOT!! I am fearful of purchasing another after seeing the damage and that this model could have caused a fire! So, Buyer Beware! If you love your G.F. grill and want to use it, just keep an eye on the bottom of it, especially this model that runs so hot that the coils can burn through the plastic covering the unit!! I would suggest sitting it on something that can handle the heat too! :(  I'm giving it 1 star because of the potential danger, even though it was reliable and cooked well while it lasted.
I found the bottom gets hotter than the top, causing uneven cooking. I also found the top plate shifts to one side, causing the opposite side to fall when opening the unit. I think it is not worth spending the money and like the older model better, it also has temperature controls.
So far, so good! They've made some key changes to the Foreman Grill since the early model we previously owned:* Unit now has temperature control + timer* Top & bottom no-stick cooking plates can be removed for easier cleaning! !This is a handy cooking gadget for those of us who hate to cook (and who hate a lot of cleanup). My only quibble is that they could have included a 2nd "grease catcher" tray.
Needed something to cook bacon on like my old Foreman grill. This was not it. Top plate does not meet the bottom plate so I had to flip bacon. No better than a skillet. Also did not heat to highest setting.
This think takes a long time to heat up to temperature and it cooks uneven because of the way the top rests on the food. The food cooks faster at the top than at the bottom. I havnet tested it yet, but I have a feeling this thing is eating up a lot of my electric bill too. The whole point of a Forman is to be fast convenient and healthy but with the long heat up time, slow cook time, and long recovery between each application of meat, this thing is more of a hassle than its worth.
Lesson learned, at the cost of $79 bucks. I would not even give this one star were it not for Amazon's insistence that I do so in order to post! Zero stars!Ok, revising my original review! 4 stars!! We received a replacement from Foreman, no help from Amazon, whatsoever, and the grill has been going strong. Still cooks a little unevenly, top has nice grill marks and bottom of meat is not seared. It has served this family of four well for the last few years now!
and the smell completely disappeared in minutes. The same thing happened with my new oven, my new microwave, you get the idea. Also, the reviewer that thinks this cooks unevenly or does not grill correctly, hello, all you have to do is flip what you are cooking one time halfway through and problem solved! I have cooked super thick steaks on this unit and they were perfect on the outside and medium well on the inside. The only complaint I have about my time with my GRP99 is not the fault of the product, but my helpful but extremely short-sighted boyfriend who cleaned the plates with a steel wool pad and completely rubbed the teflon off the nubbins on the bottom plate after the very first time I used it.
I bought this grill because I thought it was one of the better units. The unit has sort a delay when you chance the temperature setting. Sometimes it appears to heat up and other times it doesn't. Even when it reaches the cooking temperature of say 400F it seems to cool down too much. I put my IR temperature sensor on to prove this and it drops well below the 400F temperature. The unit appeared to be a refurbished one although the ad was saying it was new. The buttons feel like they are well used.
Answer: I found that the thicker the food item, the harder it was to get the top heated equally to the bottom - simply because the back is hinged (and with a thick item, it would then leave the top, front more exposed).  However, the top of the unit does heat up quite well.  Sometimes, I would need to readjust the food halfway through cooking by moving front items to the back, flipping them, or butterflying the items if it was a bit too thick.  Still, I really liked this unit and used it continuously for 2+ years.  I also submitted a review that is not published yet, so just as a cautionary warning:  The unit I bought ended up heating so hot (after a few years) that the coils burned through the bottom of the plastic covering and began to burn my counter top!!  Luckily, I saw it early on and stopped using it!  It was a fire hazard.  I called the company, and they sent me a replacement (though sadly, it was not the same type or quality).  I miss this grill, as it was the best of three that I've used in the past ten years!  I'm debating if I want to take a chance and buy another of these, hoping it was a fluke that the coils burned through the bottom!  If I do that, I will certainly set it on something that can tolerate heat so as not to risk a fire again!  I would suggest, if you purchase this, that you do the same - just as a precaution!  This was a great grilling machine up until my issue with the overheating coils!  I really miss it!  :)
