I ordered the Pre-Cut 4D Carbon vinyl for my Mazda 3. The vinyl itself is great quality and the print looks fantastic, from a distance it looks exactly like real carbon fiber. The problem comes during installation, where the adhesive is pretty weak. The adhesive in some Chinese wraps are a bit stickier than this vinyl, however that being said if you grab some edging pens then you won't have problems with sticking.
It might just have been the Pre-Cut stuff I bought but I noticed that holes didn't exactly line up. The handle vinyl wasn't long enough to cover them completely which was incredibly upsetting. For the most part the vinyl covered the OEM silver, but it always felt like the holes were a bit off.
+Fantastic Vinyl Quality
+4D Carbon looks realistic
+Pieces came Pre-Cut saving a TON of time
-Pre-Cut pieces didn't always line up or wasn't big enough to cover pieces entirely, which is unacceptable at this price point.
-Adhesive used on the vinyl is pretty weak and WILL require an edging pen to ensure proper adhesion.
Should you buy it?
What do you value more, quality or time? If you are new to wrapping or are willing to deal with pieces not fitting perfect and having to buy extra adhesive, then YES this vinyl will save a LOT of time and effort on custom trimming and is durable enough a novice won't likely over heat it and ruin the pieces.
If you have experience wrapping or want perfect coverage of your interior then I would stay away from the Pre-Cut pieces. The end result just isn't worth the price you pay and the time you save by cutting everything custom. The vinyl itself is actually decent quality as long as you buy extra adhesive for the edging.
