This is a good company, delivery is prompt. I have bought about six of these charger sets, distributed amongst family, I like their convenience very much, there's one little hitch, and as I have three different listening devices, ear buds, head buds (cosy) I'm wondering if they chargers have a life expectancy as they do not always charge the listening devices. Because I have three different types I don't think it's the actual buds etc and wonder if it may be the charging cables and attachments. Would be interested to know if anyone else has experienced these issues? If it is the STATIK I'm sure that the company have a good after sales service, so I may contact them for their advice. All good.
