I had been reviewing several rear window louver/valence units from the major big name aftermarket players, like CJ Pony, American Muscle and Amazon. I even ordered a IKON V2 and it arrived and was basically very poorly made, very thin in thickness of material and poor finish. Just a box and a clear sheet cover. Sent it back. Came across GlassSkinz. Called and was connected to the owner who spent about 30 minutes on the phone answering my questions and concerns Great guy. So I took a chance and ordered a Techno 1 S550 in Raw Gloss Black. Unit arrived and was a massive upgrade in fitment, finish, quality and even the shipping container. Wrapped in 1/8" poly foam, then sheet wrapped in clear plastic sealed. Heavy Duty shipping blocks in the slots. Marine Grade ABS, not the the thin "paper-plate" stuff from IKON. Finish was top notch. This product is worth EVERY dime over anything else I looked at and even ordered and sent back. 3M tape was pre-applied and cut. Adhesive accelerator pens were included. Plus a ton of marketing material. Overall you simply get what you pay for. And this product is worth more than what I paid. Is it more expensive than IKON? Yes. Is it worth it? YES, every dime. The Raw Gloss Black looks outstanding on my 2020 California Special Mustang GT in Shadow Black body color. I had Ford Performance apply the GT-350 Factory Upgrade prior to taking delivery to the intake system which is the manifold up, new throttle body, intake system and a crate of parts. This also came with the Ford Performance limited edition side rear quarter window scoops you see which are not full sized to make the rear quarter glass look like a pillar, and the window scoops have matching Ford Honeycombs inside the pocket that match the GT-CS body scoops and hood inserts, Roush racing fender brackets and hydraulic hood struts, no prop rod, and LED side markers and a LED backup light. Love the way this thing accents the tail lights from the rear. Thank You GlassSkinz. If you are thinking you are spending too much, forget it, you will be amazed at the difference this product presents over others.
