Never knew anyone with one, but I always wanted one when I was a kid. Magazine coverage made them look awesome. Now I'm old and still want one! But it seems they're a bit high maintenance...
I've got a one that has long since died due to the leaky capacitors. Tried to resurrect it but no luck so far. May look to salvage the chips for a full mainboard replacement at some point.
I had a friend who had one and it looked amazing! Just like a real console attached to a TV, and indeed it was basically a portable Sega Master System in design. I only had a gray-scale GameBoy so the display on the Game Gear was incredible by comparison.
I do remember my joy, when finding out that instead of feeding it with batteries, I could even use the power adapter of the master system to play with the Gamegear. 😄
There was demonstration one in our local Kmart in the electronics section. It had sonic the hedgehog on it. Everytime my mom would take us to the mall, I would beeline for the Game Gear and Gameboy they had and play until she got me.
Bought mine in the 90's from a high school friend. Got the car adapter and it was a lifesaver for the family road trips which we did a lot of back then. I kept it even though it stopped working years ago. Then learned how to recap it during the pandemic and got hooked to console modding. That was a slippery slope. I've since bought, fixed, and customized 6 game gears with custom-painted shells and installed the different variations of screen and power upgrades. Now I find broken consoles and fix/upgrade them as a hobby. There's something so satisfying about bringing life back to gaming hardware that people have given up on.
