A real pleasure working together! I especially appreciate that the team doesn't dodge problems — they fix mistakes fast. It's great to work with professionals you can rely on even in non-standard situations.
Great store, great service, great prices — all was perfect 👌🏽
Very good service. A clear, easy-to-use online store. After the purchase you get a confirmation and a tracking number. Delivery took a couple of days — and if you don't want to wait, you can pick the item up yourself.

Very nice socks, bought as a gift.
Really fast delivery. Thank you.
Wide range of winter (skis, snowboards), summer (moto gear, hiking footwear) and electronics (drones, gimbals, mounts) products. They also offer drone pilot training.
On our way back from the North Cape we stopped by to replace the rear tyre on the motorcycle. Unfortunately they had no road tyres in stock and, it being Saturday, no mechanic either — but they went out of their way to find us a tyre shop that could help. Thank you very much!
