Review on 🔧 Triwing Screwdriver Set & Game Bit Tool Set with 5 CR1616 Batteries and Tabs - For GameBoy Color and GameBoy Advance Games - Individually Packed Batteries by Cathy Khan

I bought this kit to replace a backup battery in one of my Gameboy: Metroid II games. I immediately checked the batteries with my multimeter and found the 4/5 to be within spec at 3.3V. The 5th as shown in the picture was dead on arrival. Then I tried 3.8 bits to be used to open the game cartridge. It was useless as he wasn't holding the screw at all. Luckily I already had a bit of the same size from another Luki company so I was able to open the trolley and change the battery with one of the workers. On a positive note, I tried a triwing screwdriver on one of my Gameboy Advance carts and it held the screw well. I don't have Sega cars, so I couldn't test the 4.5-bit version. I do not recommend this kit. At least two items were defective. Looks like a quality check error. The only reason I didn't return the product was because I didn't want to wait a few more days for a battery replacement.
