RetroSticks® for SEGA Game Gear - RetroSix

There is no documentation or easy to follow document guide, instead, you have to watch a 24 minute youtube video.

The LEDs and the potentiometer screws are not in the most easy to discern places (which LED and which screw goes to which direction? There is no silk screen to tell you! Gotta look it up! And because there is no documentation, You have to skip around the you tube video to find the part where he mentions it.)

Also, The calibration makes diagonals basically impossible. You can kind of chose if you want a diagonal on up right OR down right by biasing the stick in that direction... but not both. So top down games with 8 direction movement are basically unplayable.

The joystick itself, being a Nintendo Switch stick, is comically small. And looks ridiculous. I understand this is likely availability of parts, and perhaps a better sized stick could be used in the future.
The dust cover is barely larger than the hole in the shell, so it is always popping out of position, and looking tacky.

Over all I was excited to have this mod, but the pay off was lack luster and disappointing. do not recommend.

No matter how it was calibrated it would still input up right when holding right and down left when holding left

Once calibrated, as per the YouTube video, this stick is a great option that feels much more natural than the older style directional pad. Easy solder points. Well worth the money.

I installed this in a custom game gear kit. I had immense difficulty trying to calibrate it so that it's balanced enough in all directions, but I still get some vertical drift with the horizontal directions and it makes controlling games or navigating menus overall quite difficult.
This came with a rubber diaphragm to cover the opening around the stick. this however was of such a size that makes it look comical, bulging and moving uncontrollably, and overall looking worse than without.

Great seller recommended

The rubber around the stick could be a little bit bigger by 1mm to stop it popping out other then that its awsome no issues for installation
