Update: I'll never order from banggood again. Yes, they have good prices and they ship quickly. Just hope that you don't have a problem, because their customer service is terrible.
I ordered an RRT01 from them. They shipped it in the tiny factory Jetbeam box without putting it in a larger box and using bubble wrap or packing material of any kind. Needless to say, it was Dead On Arrival when I got it.
The contact forms on their website to open a return ticket, or to do the live chat will not let you submit or open the chat or email for anything regarding after sales or returns. I had to trick them into thinking I was inquiring about a product to buy to finally get an agent to chat.
So I jumped through all the hoops - take photos, take a video, pics of the order, the sku number, etc. They said they'll resolve it in 24 to 48 hours. That was a week ago. I've been emailing them, and did another live chat, and just keep getting the runaround. They try to say they replied, and are waiting for me to reply back, but I tell them I've replied back every day, and they just keep on with the same 24 to 48 hour thing. I submitted the photos and video AGAIN, and the same runaround. Their return emails are the same copy / pasted generic reply every time.
When I ask them the direct question about when will they refund my paypal account, or send me a prepaid label to return the item, they won't answer the question. What a bunch of scheisters.
I contacted Jetbeam. They got back to me the next day and had me to check if the tail cap ring was tight, which it was, but now I probably won't get to talk to them again until Monday. Hopefully they will replace the light, or get some action somehow.
When I placed that order in the middle of the night, half asleep, I had been thinking that they were in CT, not China, but I was wrong. I think that's battery junction. I cringed and had a bad feeling when I realized where it was coming from, and rightfully so. Never again.
Buyer beware. Buy from US suppliers if you live in the US.
