Big difference in prices for camber kits (to correct rear tire inner shoulder wear)

[Coopr]

My 2019 X is experiencing the issue that so many of you have had: very fast wear on the rear tire inner shoulders.

I understand I need a camber kit and these are three options.

$230 - Rear Camber Kit Tesla Model S/X Hardrace Q0601

$499 - MACSBOOST Tesla S X Camber arm set - MACSBOOST.com

$644 or $844 - N2itive SX-2 Rear Camber Arms - Fixes Tesla X/S Crazy Rear Tire Wear!

I'm wondering why the prices are so different - $230, $499, $644, or even $844 - even though they all do basically the same thing?
