Very useful, but the user manual should be updated. From my experience there is no way you can execute 10 drying before "recharging". They say you need to put them in the oven for 2 hours to reset them. This works, but after use they advise putting them in their plastic bag and do that 10 times before putting back in the oven. However, from my experience, this does not work. What I do is, between use, I leave them on a heater, near a fireplace or on a hot air outlet. So when I am skiing they are drying, when I am not they are in my boots. This has been efficient, and they maintained their efficiency over a 10 days trip like this. I still put them in the oven between ski trips, so I do not know past 10 days if that still works. With that little modification on their usage, I have been satisfied. If you follow their direction, they will likely only work on the first usage, second will leave your boots wet.
