Found cheaper tesla model 3 floor mats on Amazon that had only 1 review. Took the risk and bought it. They fit perfect and I love red liner on the mats that goes very well with my red model 3. Basically these mats are the same size as the original floor mats that came with Tesla. I haven't used other floor mats like Maxpider so can't really compare them. These are certainly good for the price ($69)
