This TV tuner accessory for the Game Boy Advance came as a great surprise: it's a great idea that actually works. It's very simple to use, clipping securely on to the rear of the GBA using the cartridge port (the tuner has a cartridge slot, in which a game must be inserted for it to work); extend the aerial and switch on your console. Once you're fired up there's a wealth of options available to you via a combination of the GBA's buttons: auto-tune, contrast, brightness, PAL type etc. Auto-tuning takes around two minutes, and the picture quality is very impressive, only restricted by the limitations of the GBA screen. The sound quality is also clear. Quality can be affected, however, if you try to use it where reception is poor--among big buildings, in moving vehicles etc. The tuner can also be connected to DVD players and other consoles, which is useful if the other TV in your house is being watched. Battery life (4x AA batteries) is around 110 minutes; the unit comes with an AC adaptor and Blaze has also indicated that they intend to release a car adaptor. All in all, this is a gimmick that turns out to be quite functional and surprisingly effective
