The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer.

With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

¿Snake oil? At least it worked for me
Style: Modifier, Style: Modifier
Very cheap compared to buying it locally, here in my country. Used the Ceratec with the Leuchtlauf High Tech oil. 143K miles on my 2.5 mk6 Jetta. It started to make some tappet/lifters noise, very minimal but it was there. As soon as I started the engine, and about 30 minutes in , I could clearly hear the difference. How I heard the difference? With the hood closed now I can barely hear the engine, unless I put my ear close to the grille. Now I only hear the working injectors. Totally recommended. Can’t speak about gas consumption, I’ll have to drive 500-1000 miles to speak confidently. Recommended for giving older engines a longer lifespan. Update: After 15 days or so, and about 150-200miles later, I noticed my Jetta’s engine feels lighter and smoother. No placebo effect, it’s just there. Since I bought two Ceratec bottles, I used the second bottle on a Mitsubishi Outlander Sport with the Mivec 2.0 engine. These engines are quite noisy, specially the injection noises, and I had a very concerning lifters ticking. I did my oil change yesterday, and today the ticking is gone, all I did was use Liquimolys engine flush, Valvoline oil and the Ceratec. I’ll post an update if I get better fuel economy and smoothness on my Mitsu.

Durable and well fitting
Durable and well fitting. I drive a Honda Accord 2014 and when the under engine covers started falling off I used these to replace the ones that came off. They work well and the prying tool made replacing the retainers easier.

This product has many different sizes making it easy to fit clips in other parts of the car.
I was working on my grandson Honda. It was missing the plastic clips to hold the fender liners in place. This worked great and helped hold the fender in place. I used the puller tool many times on other plastic parts on the car.
