This seemed like a good idea, and I bought it without doing any research. After I brought it home, I read the reviews here and saw that some folks had experienced the glass breaking immediately. I used it just once -- for an oven-roasted leg of lamb for Christmas dinner, and after the estimated time took it out to read it. The meat reading seemed right, but the glass was cracked. Luckily no pieces seemed missing, so I could still serve my guests. Also luckily, I had bought it locally and could return it. I hope Polder takes note of these several comments and does something about this somewhat risky defect. I can't recommend this at all, because of this problem.
