Photo of a photo of tulips

Has anyone tried Mixtiles? They advertise on Facebook. I tried them for the first time and I'm pleased with the result. You send them your photos - it has to be done via their app - and for £9 each you get 8" square lightweight photo tiles. They stick to the wall with an adhesive strip and they say the photos can be moved as often as you want and will re-stick but not mark the wall. So far so good. . .
