I've been doing constant quad research the past month. GearBest has a horrible reputation!
GearBest are one of three online toy/electronics/quad stores online - owned or operated by the same people and in the same office. ( anybody doubting the veracity of my comments - search for and read my thread Syma Saga)
The other two are EverBuying and Tiny Deals. I suspect there are others - but I never bothered to check after proving my original statements about these three - and others who operate more than one website/store.
There are more like these who have bad reps... but you need to understand that China does not have the same Consumer laws as have most if not all "Western" countries - and copyright law seems none existent with the copies/clones/fakes on sale.
GB like others - send out goods known to be defective ( see my Syma Saga thread) they rely on the fact that return shipping at your expense - is not a move many will take having already been conned! So they offer a refund - GB et al do not "refund" to your CC or PP - they institute a "store credit" - which forces you to use to buy something else.
Having traveled that path over the course of literally weeks of delays and "ticket" message going back and fore - all designed to wear you out and go away - IF i was to go back I would have started a PP dispute - but again - PP expect you to return the defective item.
These stores know you will never buy anything again - customer loyalty is not an issue to them - its internet business - world wide and years already passed of amassing bad reputations and conned customers - has not diminished their income... so why worry about one guy with a quad that wont fly - or whatever.
I am one of the biggest critics of the three stores I mentioned - because they caused me weeks of aggravation and lost cash. I decided to try BanGgood.... My first order - they had no stock - this is how I stated with EverBuying and the WLToys quad I ordered - asked for refund - got store credit - BG without me asking cancelled the order and refunded back to PP. I have used them for 5 other orders - and I have no complaints.
Ye sthey have a forum and yes there are posts on it that complain of getting broken or defective items - but BG always sort out the problem with replacements or refunds.
Checking a lot on the forum and many seem to have ordered something of low value - complain online - but often do not follow through and seek a refund or a replacement - or want to wait another 3 or 4 weeks.
I did have a late delivery and BG suggested I wait 60 days - and if not arrived they will replace. They know that sometimes deliveries do sit somewhere waiting a space in teh Consolidated Shipping hub system that allows cheap freight charges WHEN there is available space. Packages can travel in a zig zag pattern from different air cargo routes to get to a final destination - it takes time.
I made on order on HobbyKing last Thursday - opting for a $20 DHL shipping fee to get here before Christmas, it arrived yesterday - Sunday delivery due to the seasonal rush - had it not been for that - then it would be here today Monday.
That said a while back I ordered a receiver for a Devo 10 - from Banggood - it arrive din 5 days from order and from Melbourne which is about 500 miles away. I asked how it was that it came from inside Oz.. they did not answer.
I have found a (to me) new online store selling quad stuff - I have a $20 sample order in transit - to test the system.. and will get back with what I find.
Depending on your country - Amazon and eBay are often better options. With eBay you have protection and often the online store and the eBay store are all waiting in Goods Out offices in ShenZhen - for the same items.
