Can’t believe I am asked for a feedback review for a 90 quid lamp that has been reported as faulty upon receipt, and I’ve yet to hear back what you plan to do to resolve the problem. Lampsy support advised that the lamp has to be used with a specific USB charger, and that the unit doesn't work with any USB cable and charger. They are modifying their website to reflect this specific detail. The lady could not be nicer and, agreed to refund the unit, and emailed a pre-paid label. I’ve modified my feedback to reflect, whilst disappointed, the company resolved the problem to my satisfaction.
