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.

It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. 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. *Britax cannot guarantee 3-across fitment in all vehicles.

Well, worth it
Well worth it my robot vacuum stopped working properly. It would not find it’s station and would wonder until the battery died. I was able to get a refund and buy a replacement.

Fast and no hassle protection of your expensive product purchases
Had an issue with my expensive floor cleaning robot breaking after less than 2 years (i.e. 1 year in to this 3 year extended protection plan). After submitting an online claim, they sent me a 1 page form to fill-out and provided a shipping label to return the large and heavy robot. Within 3 days, they sent me an email saying they couldn't repair it and provided a FULL-REFUND via an Amazon gift card # which successfully credited to my Amazon account.

HORRIBLE CUSTOMER SERVICE!
Bought 3 year warranty for new Dyson vacuum for $76. On day 2 the battery for vacuum would not lock into place. In order to have a functioning vacuum as quickly as possible, I purchased a second battery from Amazon. That resolved the problem, proving the battery was the problem, not the vacuum. I filed a claim with Assurion, which included sending photos, receipts, etc. The claim was still "processing" for a week. I got on a chat with Assurion, and for nearly an hour I tried to explain why it was unnecessary for me to return the whole vacuum. I asked for a supervisor, but they advised me to call because no supervisor was available. I called, and after finally getting through the computer system, I got the same run around. Finally a supervisor came on the line to tell me that this was actually an Amazon or a Dyson problem, and that I would need to return the entire vacuum. Also they would not "reimburse" for the battery I purchased. I never wanted reimbursement, I only wanted a functional battery - which is what I paid for. The supervisor told me I could "contact" Amazon. Everyone knows there is no human to contact at Amazon. You can keep the product, or you can return the product. As previously stated, I do not want to return the vacuum. Finally, the supervisor connected my call to Dyson. They refused to help me because I purchased the vacuum through Amazon. After two wasted hours, I ended up just where I suspected I would...without any help at all. I am going to try to "return" the useless Assurion warranty.
