Enjoy safe travels from birth to big kid with the Britax One4Life all-in-one car seat. This car seat features 4 configurations, including rear facing infant car seat, rear facing toddler car seat, forward facing 5 point harness car seat, and forward facing high back booster seat. Start out with the rear facing car seat for infants and toddlers, then graduate to the forward facing car seat and booster car seat for preschoolers and big kids. ClickTight technology makes it easy to install your new baby car seat with confidence. Simply open the seat, follow the path to thread the seat belt, buckle it, and click the seat closed. The One4Life all in one car seat is outfitted with a high-strength steel frame, a SafeCell crumple zone, and a patented V-shaped tether. The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe. The easy-pull adjuster lets you move the 15-position headrest and no-rethread harness at the same time, so you can find a secure fit in seconds. Quickly adjust between 9 recline positions and use the easy-read level indicators to find the correct angle. The Britax One4Life comes with an easy-to-remove, machine-washable cover, and the knit construction is naturally flame-retardant.

  • EASILY CONVERTS: From a rear-facing infant seat (5-50 lbs) to a forward-facing 5 point harness seat (22-65 lbs) to a high-back belt-positioning booster seat (40-120 lbs)
  • CLICKTIGHT INSTALLATION: Unobstructed seat belt paths clear the way for confident installation, and the automatic tensioner takes care of the tightening
  • PATENTED V-SHAPED TETHER: The staged-release stitches helps slow and reduce forward movement during a crash
  • SAFECELL TECHNOLOGY: Acts as a crumple zone, absorbing crash energy to help keep it away from your child
  • BUILT-IN COOLING CHANNELS: The ventilated mesh helps improve air flow to keep your child comfortable
  • NO ADDED FR CHEMICALS: Naturally flame-retardant fabrics and foam with no added FR chemicals
  • STAY-PUT, SOFT COMFORT PADS: Helps prevent the harness from rubbing against your child’s delicate neck
  • FLIP-FORWARD BUCKLE PAD: Stays out of the way for easy boarding; made with extra padding for premium comfort
  • COLOR-CODED BELT GUIDES: Make it easy to route the seat belt through the correct paths for rear-facing, forward-facing and booster mode
  • HARNESS HOLDER SLOTS: Help keep the harness straps out of the way while your child gets in and out of the seat
  • 2 LAYERS OF ENERGY MANAGEMENT: The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe

Rugged Watch at Good Price
Color: Black, Gray
I originally wanted a G-Shock but I have a small wrist and G-Shocks come with cases that are too big for my 6.1 inch wrist. An alternative? I bought the Timex Ironman. It has a rugged look and many of the features of a G-Shock but at a lower price. Small wrist? Or don't want to spend the money for a G-Shock? This is your best bet.

GREAT sports watch! TERRIBLE DELIVERY!!!
Color: Black/Digital/Green, Color: Black/Digital/Green
I am a Big Fan of TIMEX and I own several models, this one is my all time favorite. I've ordered it with so much excitement, but received an opened package, opened box, that was torn and destroyed, my Timex hanging out of the box!!!!!!!!!! COME ON People - We are paying our sweat money for this, at least deliver it with respect! The watch is a work of art and I love it! It's a good value for money, great in size, fits right on your wrist, feels so good, looks so cool and is super accurate! So, Thank you TIMEX ! I wrote 4 Starts because of the terrible delivery service!!! Not the watch! AMAZON - Please be respectful.

Simple and reliable
Color: Black/Digital/Green
I love the simplicity and reliability of this watch. It has only a handful of features, but they're all easy to figure out and use. The display is quite readable as well, under just about any conditions. This is an example of good design that doesn't try to do too much. What it does do, it does well. Good price too! These watches are durable and will last a long time. Battery changes are easy too.

Beautifully simple
Color: Black/Digital/Green
My son has worn a smaller version of this watch for a few years. After trying a different brand lately, which broke way too easily, I found this one on Amazon listed as "Used - Very Good" condition. I received what appeared to be simply an open box item, otherwise it looked brand new. This watch fits me really well, and is not clumsy on my wrist, it does not get in the way of everyday motions. For me, it's just the right size. It is also pretty intuitive to use and set the alarms, etc. It has 3 alarms, each with a different sound. It can be worn in the shower without issue, I have not tried a swimming pool, though. It feels tough and durable, as my son's has proven to be. I'm very happy with this purchase. *** Update: I spent considerable time in swimming pools recently while wearing the watch. It's still as good as when I opened it. Still 5 stars. *** Update 2: a year-and-a-half of wearing, and it is performing really well! All the buttons and words on the watch are still in very good shape and easy to read. I wear this every single day. I don't put it through the wringer every day. But, I did spend a full week sailing and snorkeling last summer in salt water with hours each day in the water. It still looks and works the same as the day I bought it.
