As a very long term (472 order) customer with Banggood I was very disappointed to have had to close my account with them after they stooped to stealing money from me. So here, in no real order, are six solid reasons to simply buy elsewhere.
First, the delivery times. Recently they have slipped severely, and on a majority of orders, I've been waiting over two months for most of my orders this year, which is totally unacceptable.
Second, the packaging is terrible, and any item at risk always arrives damaged. You will not be compensated for this damage. Items are simply tossed in a bag with a wrap of thin foam, and get absolutely no crush protection. Larger items like RC planes and quadcopters are simply shipped in their merchandising box which is not made for the rigours of budget mass postal handling and as such usually receives enormous damage, again, with no comeback.
Third. structured reviews. There has been a lot of sneaky thought put in to the latest Banggood review system which rewards and entices customers to write a review immediately upon receiving the item. There is little time for real testing, and once confirmed as received, you cannot go back to review later. They also screen all of the submitted reviews and only publish the good ones. I have done over 470 reviews there, and none of my bad ones were ever published, so for that too, they have zero credibility, and it actually suggests that they are willing to defend poor quality products that probably should not be sold.
Fourth, Sneaky charges. Banggood have a points and coupon scheme, it's so utterly convoluted it makes your head spin. Should you decide to redeem your points or crazy item specific coupons, you should take notice that later in the transaction, you have been charged some bogus shipping charges at checkout time. This is just a plain grab back, and it can be reversed, but you must examine those final costs, and look for where the extra's have been sneaked in.
Fifth. Warranty. This is not a word that Banggood understand or support. Usually you are faced with a total loss if your product doesn't work for whatever reason. They never ever refund what you paid, if you manage to protract through the weeks or months of emails with video evidence, correctly sized and formatted photographs, and then more video's, they may (very rarely) offer you a small percentage back in refund. To anyone in the real world that is simply theft, but to Banggood, it's the business model.
Sixth. Price. Being a fairly young and new mega retailer, Banggood have recently grown into an ever more faceless and disconnected massive corporation, they have crept their prices up compared to the numerous smaller resellers, and luckily for me, much cheaper options are always available.
In summary they fail on Delivery time, Packaging, Trust, Credibility, Warranty, Communication and Price.. what else is there to fail on.. just range maybe.. well, they're usually out of stock with much of what I need, .. hmmm
So i ended my dealings with them, which was quite liberating, as I have since found many better, cheaper and faster sellers, yet to be warranty tested, but I'm happy so far.
