First a word of caution: when I think "bike", I think "motorcycle", not bicycle. I know next to nothing about bike lights, other than that DX sells a ton and that they tend to be a bit expensive. This may very well be too good to be true. I don't know. Proceed at your own risk.
i smell a rat ..listings don't just disappear . you can always see what has been sold and for how much and the sellers name ,rating ,feedback etc.. nada
I remember when it became popular to sell items that don't exist and then run. One guy was able to rake in $1 mil in a few weeks without delivering a single product. Of course, you have to get it done in that short of a time span because you need to avoid negative feedback to keep the buyers coming.
That’s true, and I see it often. Some Chinese sellers do their work OK, they get a lot of positive feedback for a year or two, and then they just stop sending items and then disappear!
In this case, the seller didn't wait to have thousands of positive feedback, he just did it.
