I am very satisfied with this little radio...........eventually!
I wanted a portable DAB radio. It wasn't made clear from the packaging that it also requires the purchase of a rechargeable insertable battery cell to run away from the mains. When the cell came, I found it was pretty difficult to fit in. It's a tiny little port awkwardly placed at the bottom edge of the battery compartment. I was at the point of giving up when (hey presto!) suddenly it slipped into place and it has been working very nicely ever since.
I've been listening to it most of today and the battery is still going strong, so the claim of 20 hours 'battery' life seems justified, this seems very good for a DAB radio. And it is very easy to recharge - you only need to plug the radio back into the mains and it will charge the cell for you. The sound quality is very reasonable for a small radio and it also works well with headphones.
I agree with those reviewers that, because of the problems discussed above, it would have been better for Pure to sell the radio with the battery already inserted. If you are not technically minded or do not have steady hands I would think twice re purchasing this radio with the purchase of the cell combined in mind.
