Dominator EFI Vehicle Management Systems are intended for all engine applications, from street to unlimited high-end racing applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8 cylinder running water-methanol injection? No problem with Dominator EFI. How about control a 4L60E transmission as well as the fuel and spark on your street rod? No problem. There are also enough inputs and outputs to allow the Dominator VMSs to serve as their own data acquisition and control module. The Dominator VMS will eliminate the need for additional controllers as they are all contained in this one unit. The only thing limiting the Dominator® Vehicle Management System is your imagination!

Just ok
Size: 5 Fl Oz (Pack of 1)
You get what you pay for. It’s reasonably priced but I find it leaves my skin feeling dry. I need a product for aging, dry skin.

Finally a Cleanser That Works for My Daughter's Puberty Skin
Scent: Unscented, Size: 3.4 Fl Oz (Pack of 1), Scent: Unscented, Size: 3.4 Fl Oz (Pack of 1)
I ordered this foaming gel for my 11-year-old daughter on the recommendation of our dermatologist. She's at that age where her skin is changing, and we've been struggling with excess oil, shine, and the breakouts that come with it. Honestly, this is the best face wash we've tried so far. The texture is light and pleasant, it foams up nicely without being too thick or heavy. The scent is very mild and not overpowering, which is great for sensitive skin. After just a few uses, the oily shine on her skin started to fade, and the sebum production noticeably decreased. That means fewer breakouts and less irritation overall. It doesn't dry out her young skin at all. It just gently removes dirt, oil, and impurities without stripping it. No tightness, no redness. We're really happy with how it's working so far. Will continue using it and update if anything changes, but for now highly recommend for anyone dealing with puberty or oily, sensitive skin.

Rosacea care
Scent: Unscented, Size: 500ml / 16.7 Fl Oz
I have been using this cleanser for a year. It's a simple unscented cleanser that is part of my rosacea care. No irritation or tightness. When it's on sale I grab a couple. I found that applying it to dry skin first, then adding water, is much more effective than applying it on wet skin. The consistency is a little thin so it's challenging to make it lather. A great all around cleanser for any type of skin.
