I'm shopping with GB for 1 year now. I have bought 20+ products from them and have no serious problems.
Shipping to Switzerland takes 2 weeks, they ship usually the next day after purchase. GB is willing to declare parcel content for the customs as you advice. In case of problems with product the support is responsive and looking for a good solution always. GB have promotions many times so you can buy the product cheaper than in other shops.
For buying and reviewing you can get points which discount the next buying. I can recommend GearBest to everyone wanting to buy Chinese toys from a reliable retailer.
