I have bought three of these. They don't seem to last very long- my current one now makes a horrible squawking sound instead of beeping, despite changing the batteries. More importantly the pre-set cooking temperatures are not good, and there is no way of setting your own. For example to cook a joint of beef medium, I find that taking it out of the oven at about 57°C and letting it rest is about right so it is around 63°C when we sit down to eat it. However the lowest setting is 60°C, which produces overcooked meat by the time it has rested. I am now looking for a different one that lets me set the temperature alarm.
