Received a genuine carbon fiber spoiler, that fit like a glove. Came with vinyl pieces to help align and secure spoiler while adhesive sets. Installed in less than 10 mins, as long as car is clean and area is prepped. Did not come with extra 3M tape and the applied tap was not a single strip which made it a bit tougher to install. Besides that, great product, with attention to the DIY market.

The spoiler arrived in a very well secured box, and secured within foam inside of the box. Zeros flaws were detected upon inspection and the spoiler was made of all high quality parts. Installation was super easy and has been extremely durable with no issues. I absolutely love this addition for my model 3. It gives it the perfect sporty look while remaining classy at the same time. I am beyond satisfied with this product from TESBROS.

I always appreciate Ji's videos on how to install, it makes it a lot easier for us DIY-ers. I purchased this CF spoiler to give my M3 a better look. The one issue I have with this spoiler is it does NOT fit. The curvature of the spoiler does not match the curves of the trunk. No amount of double sided tape will fix this. To properly fix this the curvature of the spoiler needs to be bent (which I am not doing) to fit in to the trunk.

Love the quality and instructions was very simple and easy to follow. definitely recommend this over buying one from tesla.

I wish all my on-line purchases were this satisfactory. I am an old guy that is not very handy but this thing came out of the box and I put it on just like the YouTube video in 5 min. Fit like it was supposed to. I just hope I had it the right way up. Also, the quality and delivery was just as promised.
