In my experience....definitely not.
If you are going to be listening to FM, then the life of operation in between windings won't be too bad, but on DAB its next to hopeless. I bought one to to use in my caravan and its lucky that its also mains-driven, as I would be winding the ruddy thing ever few minutes.
There are plenty of good quality radios around these....I have about 5 models from the PURE range, which I can't praise highly enough.
Can I recommend this one for instance :::

But I would forget about wind-ups if I were you !
