I have 2 Utorch S1 Mini with Aspheric lens, purchased from Gearbest in May, when the price was $27 each.
One of them has a problem with a loose ground, and sometimes it loses the Highest mode, even on a fresh battery.
I contacted Gearbest and we began a series of email exchanges.
they asked for a video, and my order number, and I complied
they offered me a partial refund, of $7, and I could keep the light, or they would send me a replacement for $20, and I could still keep the defective light
I explained that I would prefer them to send me a Klarus Mi1C, and that I would pay the difference, $22, from the 27 I paid, to the current list price of the Klarus, $48.95
they did not want to do that, but increased their refund offer to $14.
I replied that I had paid $27, and would like to apply that to the Klarus.
They did not want to trade for a Klarus, but they increased their offer to 26.99, which I accepted.
At first they refunded to my Gearbest Wallet. I then discovered that the Klarus are sold out, so I asked for the refund to be sent to my paypal.
Gearbest refunded my paypal!
I am very impressed with the Gearbest commitment to Customer Satisfaction.
All it took was several persistent rounds of negotiation, and a video.
With the refund I was able to almost completely offset the cost of a Klarus Mi1C from Banggood, using a discount code from https://m4dm4x.com/m4d-m4x-deals/
So far so Happy!
