Incredibly recommended, if fits the game boy and Game Boy Advance carts well. Gba cards need a bit more soldier, since the battery holden needs to sit atop a chip. Game boy and Game Boy color games are just perfect. No more soldering. Get this and pass the hardship once!
Item is exacly the same with photo but even tho i might reorder it again in the future there were a problem with it (i dont know if i did something wrong when using it tho). I was expecting just to solder the holder then insert battery to make it work but problem is the iron piece at top isnt touching the top side of the battery. Therefore battery isnt working. Thats why i had to solder another iron piece to the top side to touch the battery.
