Great product! If you read the directions there should be no problem setting it up to sync to your phone or device. We tried it out cooking wrapped stuffed chicken, and it came out perfectly cooked and moist. You DO only get two prongs (the photo shows 4)so we ended up buying two extra prongs from a different site. I know this is in "the fine print" but I wish it was made more clear in the Groupon listing. I might not have caved and bought it if I had known, but now that we have used it, I suppose we are glad we did, even though it ended up costing more due to having to purchase two more prongs.
I love the product. The only thing I would like is more access to a blog that explains how to use the probe. I DID watch a YouTube video and only then found out that you put the probe into the meat from the side. I was grilling boneless skinless chicken. Do you put the probe into the meat BEFORE you do any grilling....or do you do what I did....grill for about 5 min. and then put the probes in? Great product though.
