I will never order from one day only again

I ordered a power bank with a solar charging unit. The solar charging function worked for a week and then it stopped charging on the solar function. I sent it back, it took two weeks for them to tell me that the supplier tested it and the unit does charge using the solar charging function, they then returned it to me and guess what, the unit has been in the sun the entire day today and no Charge has been possible using the solar panel function. I will never use one day only to order anyrhing ever again.
