"I googled that product and read how a lot of people destroyed their transmissions with that product that comes in a funky color (bottle packaging). In the summer when I have more time, I am going to change out the trannie fluid on my 88 Toyota truck and put in this same product."
"If your transmission is a synchronizer type and those are brass or bronze, this is the fluid for you."
"2005 scion xb (XBox). **UPDATE**. Been running this stuff for 3 days and so far i couldnt be happier, my scion was fun to drive before but now i love it, i dont know what this stuff is made of but it has unleashed my transmission, shifting is a breeze and the friggin power i have now gettin the rpms up is amazing.If you got a scion 5 speed u gota try this stuff."
"This is the GL-4 rated stuff that your old MK1-MK3 Volkswagens need, since GL-5 is a *no-no* due to certain additives which may harm brass synchros."
"Unlike other reviews, I haven't noticed any real change in shifting in a vehicle with about 40k miles."
"Expensive when compared to other other brands of gear oil but this product really works."
"Best stuff in it's class."

"I was able to use the A/C after that for 5 months until the weather cooled off."
"This was a big help during the hot days of Summer."
"A very good product."
"A/C leaked down every 2 weeks - dealer said $1100 to fix. Red Angel installed 5/5/17 - 3 months later no problems - cold A/C."
"I had 2 small leaks within my automotive A/C system, both in areas with no moving parts, best suited for this product to chemically seal as designed. After applying a vacuum to the system, I first started with the A/C stop leak, applied the product as directed, dispensing the entire contents first. When attempting to call upon the product's well stated guarantee claim with the manufacturer (Blue Devil Products), I was ultimately met with this email: Grant-. You may have seen on our website under the Warranty/Returns tab: "Any online purchases made from unauthorized re-sellers are not warranted by BlueDevil Products." The correct answer would have been, "we are sorry our product did not work, could you try giving Amazon a call first and if they are not able to refund you directly, give us a call back and we will make it right! Note: Amazon was nice enough to cover the warranty (refund or replacement at your discretion) for this product, and will do so for 365 days from the date of purchase."
"This helped for a few days but the refrigerant started to leak again and thus the air at the registers continued to get warmer each day until no more cold air again."
"As a retired auto mechanic I cannot find an explanation, sorry for the one star but right after using Red Devil I lost all AC !"
