Onestly the product seems good, it arrived in time with no damage, but it doesn't work. Probably it's because my NDSL got some other issue so i cannot test it. So in my opinion the seller is good and reliable. The product I dunno.
unfortunately the lower display didn't have insulation on the back and I blew a fuse on my DS lite when I turned it on after installing a new top and bottom screen. therefore I'm unable to say if either of the screens is working or not. please be aware of this and isolate the back of the bottom screen before installing.
