The GBA SP is processed really neat, nothing is loose, neither buttons nor the side switch, the lighting is normally lit room very pleasant and there you can see everything in normal lighting conditions.
Unfortunately, the display reflects what really is very disturbing in low light conditions or positions to the light, so in the summer on the beach you can see next to nothing if you do not sit in the shade.
The quality and volume of the sound is very pleasant, not painful sounds and usually I have the volume in the room only to max. a half.
The battery lasts quite light with 10-12 hours continuously - without lighting up to 16 hours of continuous use, the charging is completely finished after 3-4 hours.
The contacts for the Module prepare even after all these years, no problems, plugging and unplugging function smoothly, On / Off switch can also continue back and forth smoothly.
The GBA SP is play games also able GB Color-, some can be from normal display mode to Time Stretch (wide scale) change.
Conclusion: There are still many good games for this console, MMN lot better than the DS and the console is doing everything possible to offer users some fun.
