It now takes a significant amount of force to get it to work, enough that I expect that Im flexing the circuit board. Love the battery life capacity on the base charger, can keep charging earbuds when required and go without charging base for 2 days in a row. I paid for birks. The wood was beautifully made, there were no scratches or mess ups with the stain. The resolution is amazing too. In much rougher shape. There is an elastic addition around the top that loosens the fit. Will continue to order this brand of sandals in the future. My granddaughter loves it I recently bought some used 1200 mk2?s with horrendous needles on them, and figured I?d save a few bucks and give these a try.
