The DINANTRONICS X is the newest installment of the highly successful Dinan foray into inline tuning modules. Like its predecessors it is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture. It does this without affecting long term reliability or the functionality of on-board diagnostic systems when run under recommended operating variables. Unlike its predecessor however, the DINANTRONICS X is Bluetooth smart and offers convenient access to the adjustment of power levels directly from the palm of your hand.
A further advancement beyond its entry level little brother, the DINANTRONICS SPORT, X connects to additional inputs and/or has a more refined tuning strategy that yields more power as a result. For those that do not wish to (or can't) alter their stock ECU with a more robust engine flash the DINANTRONICS X is a perfect alternative to satiate the craving for "more". Whichever level of engine tuning is ultimately chosen you can be sure to be pleased by the result. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles, we have seen it all. Manipulating these signals/maps with an adept hand, all the while keeping an engine running at its best and with the most reliable power, is what Dinan is all about.

Feels very oily right after applying
Ok, NON SPONSORED review. I bought this with my own money. It’s a great sunscreen, very lightweight and goes on clear. The only downside is, right after applying it feels like straight cooking oil on your skin. It’s a horrible, horrible sensory experience. But once you give it a couple minutes to dry down, it’s completely matte and feels like nothing. It hasn’t broken me out yet like other sunscreens I’ve tried, so that’s a plus.

Works great under makeup
Excellent for the face! Many sunscreens claim they are good for the face, and blend well. This one actually DOES!! It is also an excellent moisturizer under your makeup without streaking. Just a smooth, beautiful finish. I wear it all year around The sun is just as strong and quite capable of ruining your skin in the winter as well.

Not amazing, but not the worst.
I hate sunscreen and to varying degrees chemical or mineral sunscreens. This was promised as grease free and smooth, but it comes out watery and does feel greasy, but once applied on the skin it does feel smooth.
UPDATE: I got a suntan after slathering this on my face. I would say this lasts about an hour and a half. The suntan happened 15 minutes before the two hour "clock" was up. Disappointing. Back to mineral sunscreen.

Great product makes my skin look dewy and soft with no powdery biproduct
Size: 3 Fl Oz (Pack of 1)
Excellent product. It looks white on my fingertips but absorbs as a clear product which feels soft, cool, and gel-like on my skin. I usually use it with a gel moisturizer but I think one can use it on its own.
