Prices from Gunai's own store

Read from Gunai's own website in each market, in the currency it charges there. Never from a reseller, never converted. A price we have not confirmed in the last three days is shown with the date we last saw it, not as the current price.

No official Gunai store was found for United States, United Kingdom, Canada, and Australia.

Where the store lists this model more than once (colours, battery sizes), the price shown is the lowest one in stock. Prices change; the store's checkout has the final word.
