Like other reviewers, I would expect Heston to check the quality before putting his name on the product.
Buttons are flimsy and hard to press, with silly graphic movement of the temperature coming onto the screen that takes up time when all you want is to take the temperature of the meat.
Also came with dead batteries and has eaten its way through another set in 8 or so months with only a few uses.
Probes are fab for making sure your meat is cooked perfectly, but the positive reviews are commenting on it being a probe and not as a product in its own right.
Find another brand that is good quality, my experience of Salter electronics in the kitchen is not good, even with Heston's name on it.
