Gearbest is reliable. I'm buying at Gearbest for several years. I have first hand expirience and can say that from my point of view they are not only reliable but excellent in the same time. A lot of different products offered, nicely organized on the web page with appropriate description, pictures and concurrent prices. They offer a lot of discounts, daily deals, free coupons and more than acceptable prices. Many offers are at the level of "good value for money".

Gearbest customer service show a high level of professionalism and understanding, accepting to the reasonable level customer point of view. They have fast reaction time answering on any question or problem. At few ocassions they efficiently solved some delivery problems.
