The carbon fiber spoiler, itself, is very nice. It looks great on my Model Y. The spoiler was packaged well and arrived quickly. It's feather-weight, so I was happy to see it in the box when I opened it. The only issue I have with this purchase is the double sided tape. First, the tape was not affixed completely to the spoiler, so when removing it from the box it became twisted and tangled. Next, I noticed that the tape didn't stick very well to the spoiler so I figured it wouldn't stick very well to the car either, but it did make it easier to peel off. Then, I purchased (from Amazon) a roll of 1/4 "OEM approved" 3M-brand (specifically made for car body moldings) for $30.00 (20 yards) and used that instead. I strongly recommend using the 3M tape for any adhered moldings - Night and day difference in adhesion strength compared to what was provided. Once installed, witht the 3M tape, the spoiler looks better than the OEM fin that was damaged by my garage door (doh!), in my opinion.I heard about this brand from one of the YouTube review so I decided to try it.The product weight is very light since it’s real carbon fiber. I did not noticed any issue other than the product can use a better adhesive.Here are some advice that I learned which should help others install it properly. However I recommend watching some installation YouTube videos first.1) clean the spoiler section on the car with rubbing alcohol.2) pre position the spoiler on the car and make sure both left and right end does not have any gap. Don’t worry about it being center. This is to avoid the edge from lifting apart down the road.3) with the spoiler on the car, use blue painter tape to mark the spoiler position.4) put a tape on the spoiler and body in the center, left, and right for guidance and draw a line on the tape.5) add 3M adhesive promoter on the spoiler section of the car and wait until dry (1-2 min)6) remove the tape from the spoiler7) careful and slowly position the spoiler on the car. Don’t put any pressure until you are happy with the position8) use a heat gun and warm the spoiler adhesive while on the car9) put pressure on the spoiler For about 1 min after you are satisfied with the position.10) use the blue painter tape to hold the spoiler in place for about 48-72 hours.That’s about it. Enjoy! Just remember, make sure the left and right edge does not have any gap without any pressure, otherwise, the edge will start peeling apart (common issue with Tesla spoiler). I heard some owners use strong sealant as a solution.I really like this spoiler, the quality is good and it looks good on the Model 3. The only thing I would recommend is that you add some adhesive before installing it. Furthermore, make sure to measure well and install it correctly otherwise you might have issues in which the corners might start sticking up. This problem is not specific to this spoiler, it's a general issue with spoilers on the model 3 and the M3 tape that comes with the spoiler.Carbon fiber spoiler appearance is good; I didn’t see any visible manufacturing defects or damage upon delivery. The spoiler was well protected during shipment. The spoiler isn’t a spot on fitment as both ends did of the spoiler does not curve to the shape of the trunk, so the ends or tips of the spoiler naturally pop away from the trunk; the adhesive isn’t strong enough to hold it against the trunk lid. Though the cost of the spoiler is a quarter of Teslas spoiler, I would have hoped for better fitment still. I think later down the road the spoiler might delaminate overtime, and I will have to remove the spoiler and reapply new adhesive.I live it but don’t fit model Y 2022 perfectlyGood quality fits well, but the 3m adhesion tape is weak and will need to be reinforced with a stronger tape.Recommendation is to seek out a stronger two faced tape to properly secure this.Looks good....But packing needs to be better! Mine arrived in box but kinda flopping around. It was rubbing against the box and that scuffed up the matt finish. I didn't notice this till I stuck it on my car. I'm stuck with it now I guess =/Its worth it for the price but I found that it doesn't fit the best on the edges. I would take the time to line it up first and mark of 5" from both sides. Also the tape was week and i replaced it with better stronger 3M VHB tape. The carbon fiber does look real. The over all look is really nice not to have to spend $800 that Tesla wants for it. Lets the hope it stays on.
