Overview:
The B&M® Transpak is the next step up from the B&M Shift Improver kit. It has all the features in the Shift Improver kit, plus it provides additional driver manual control (GM TH-400, 350, Ford C-6 and Chrysler Torqueflite only). B&M® Transpak™ kit for 1968-1981 GM TH350 automatic transmissions. Most stock automatic transmissions won't downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you're in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you've got a modified engine, and you want additional RPMs, or you're towing a trailer or driving heavy loads downhill. Stage 1. Heavy Duty is for street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort and offers normal automatic operation when in Drive. Stage 2 is for Hi-Performance street use.

good
I’ve been using the CeraVe Acne Foaming Cream Wash for a bit now, and it’s honestly just okay. It does help keep breakouts under control and feels gentle enough for daily use, but it can be a little drying at times. The texture is nice and creamy, and I like that it includes benzoyl peroxide and hyaluronic acid, so it’s effective without being too harsh. It’s not a miracle product, but it’s a solid option if you want a straightforward acne wash that does the job. Use 4% instead.

Definitely works for acne. I've used it for a few days and have definitely helped so far.

Definitely helps with acne
Cerave is a good brand for a lot of skin care products. I use their daily facial washes and now I bought this face and body acne wash. Mostly, I bought it because recently I had a zit on my forehead that was not going away with salicylic acid washes, so I decided to try benzoyl peroxide instead. With one use that zit dried up quick and disappeared in 2 days. I will say that I did let the product sit on my face for a minute before washing it off. I didn't notice any irritation on my skin or sensitivity. Benzoyl is underrated in my opinion. It's effective at getting rid of stubborn acne, more so than salicylic acid, but it can be drying so you must use moisturizer afterwards. The effectiveness also goes for body acne. Being a woman, I get those nasty painful hormonal acne break outs on my back sometimes and this helps a lot with getting rid of those. I like that it's slightly cheaper than Panoxyl and you don't need a large amount for it to work.

Great product!
I love this product!! It is easy to apply and absorbs well. It can be used by itself, or you can apply makeup over it. I feel that it has been effective in minimizing the puffiness below my eyes. I love that it goes on with a cool feeling. I have been looking for something comparable to the Eye Rever Upper I used to use from Bare Minerals and I think I finally found it!!
The only con that I have is the cost of the product. I feel it could be less.

Great Serum!!
I really like this Serum. I cant use retinol it gives me dermatitis. But this serum is very gentle yet gets rid of under eye and upper eye dryness and itchiness. It also is firming around the eyes. Definitely give it a try especially if you are very sensitive.
