At first I had to contend with the down shaking. Over time, however, it is less and less I noticed. Me the thermometer has unfortunately broken recently (my fault - have caught shaking down the sink). Because I think it is the best thermometer for NFP, I bought the same, a new and realized: The down shaking is already a torment My guess is the fact that it is a necessary evil in new thermometers and it is worth something endure..
