This was my second Vagon by Suorin. They are super easy to use, and to fill. They charge quick too. Durability wise however, the Vagon can't take it. I thought perhaps I was just too hard on my first one (dropped, left in the Sun, etc) but after my second one, I realized it just can't handle daily use before they stop taking a charge after 2 months. When plugged in, the light just flashes and stops taking a charge so I'm assuming the battery is weakening. On the pods, they're good for a 5-7 refills each and $6 to $8 per pair of replacements, it's not too bad. All in all I was happy with the performance and hit factor of this unit. But I can't keep buying the base unit at $30 to $40 each.
