I am very disappointed that Vype appears to have discontinued the Pebble. Apart from a couple of niggles, it was the perfect device for my requirements. The niggles being 1: The refills tended to leak & 2: The battery charge deteriorated very quickly. These could have been sorted with better design & quality...... I have recently changed to the E Pen 3, which is a very good device but not as discreet. I find that the refills do not last as long and at £5.49 for 2 refills they work out a lot more expensive than the Pebble. I will continue with the E Pen 3, but I wish that Vype would improve the Pebble & re-market.
