This cleaning cartridge was my last hope to revive my old GameBoy since it is the only one on the market I could find. Was worth the buy since it worked great and my GB is now fully functional again.

Was having issues with my GBA games not bottling up or it would freeze or crash mid game. Used this to clean the pins on my GBA and everything works perfectly now.

I was able to clean a couple GBCs that were either having rouble reading games or not reading them at all. End result was reading more consistently for all of them. Was also easy to clean in etween uses, but then the pink inside started tearing so I can't use it anymore. It was getting debris in the slots. Wish there were replacement inner pads to get more use from it.

Worked as it should and did a great job! Only worked on 3 Gameboys before it became unusable though which is kinda weak, but if replacements are available, it may be worth it and either way, much easier than the credit card method. Looking forward to hopefully using again as I have more consoles to clean.

Cleans the pin connector great. Very easy to use.

Very handy for cleaning console, howevery can have limited uses before the sheet inside the card is too dirty to use
