Works for me. Have a 2018 S. Wasn't sure they would work as I have ThinOptics glasses case on the back of a Speck case but they work nicely. The rubber of the guides are stiff and work against the rubber sides of my case but hopefully they will loosen over time. If not the vendor said they would work with me plus they gave me a discount for being a little late in delivery due to all the new Model 3 owners purchasing. All good
