I love it. It's not quite as authentic due to the higher resolution, but it's a significant upgrade from the AGS-001 screen. Colours are very bright and the screen brightness has settings from still-better-than-a-001 to ahh-my-eyes. The default brightness is well chosen too if you don't want to solder, I think it's level 4 out of 6.
I would prefer if your website had tutorials or instructions on the solder locations and gba sp case modification, I had to find them on youtube.
If you're concern...
