On the left - a real Tamagotchi Connection. On the right - a fake Tamagotchi (what SEEMS to be) Connection. The fake has the chain of a European Tamagotchi. Already, you will notice that the shell on the fake Tama looks cheap and generally not as well-made. The details on the real Tama are much more in-depth - the paint has barely chipped since I've owned it (years!) and the little picture of the kissing Tama's on the fake are already looking to wear down. The fake is a bit smaller, and most definitely lighter in weight. Judging by appearance on the front shell/in a package, it isn't easy to tell if it is fake or not. The packaging for the fake had no Bandai logo, so I knew it wasn't real. Packaging is crucial when buying Tama's online.
This is the packaging for the fake Tama. Where the Bandai logo would normally be, there is a blanked-out box. It does SAY Bandai on it. The rest is in Japanese/Chinese. (Sorry for the beat up package, it arrived that way)
Those two pictures (sorry, I know it's very hard to read) show the back casing of a real and a fake Tamagotchi. The purple casing is REAL, where you'll notice it reads "© BANDAI, WIZ 2004 (skip line) BANDAI 2004 (skip line) MADE IN CHINA" Now, the fake reads the SAME exact thing in the same area, but mine had some Chinese beneath that and a logo of what looks like Pacman trying to eat the Tamagotchi.
Notice that the two have the same exact background. The Tamagotchi on the left is real, on the right fake.
Lastly, the infrared on top of the pets. The real Tamagotchi's infrared is a very deep transparent red, though it is hard to see through. The fake is an extremely transparent red that you can peer right into. You'll see a small LED and another gadget next to it.
That was my attempt at helping everyone on TamaTalk tell the differences between fake Tama's and real Tama's. I hope this can help someone out there!
