IMPORTANT! Some models have exceptions depending on models and markets.

"A very good platform for purchasing equipment. It's very easy to use. The interface is quite user-friendly. I never experienced any service issues. I went underwater in Thassos, it's hard to believe, but even there it worked perfectly."

China Golden Week 2026: 15 Outbound Hotspots for October's Massive Travel Rush
What is Golden Week 2026 and Why the Travel Surge is so Big Golden Week 2026 runs from October 1 through October 7, a seven-day national holiday built around China's National Day.

That seven-day window is still enough to trigger one of the largest travel movements on t...

The 20 Best Places to See Autumn Foliage in October 2026
Why October 2026 is the Best Month to Chase Autumn Colour October is the only month in which the northern hemisphere's three great foliage regions overlap. Japan's mountain interior, the Alpine and Carpathian belt across central Europe, and the North American maple corridor all carry colour somewhere within the same thirty-one days.
