The Britax Poplar® S Convertible Car Seat is the best space-saving convertible car seat for parents seeking advanced crash protection, ClickTight® fast installation, and 3-across seating capability in a compact 17-inch profile. This convertible combines advanced safety innovation, superior comfort, and space-saving design to make every ride safer and simpler. Built with ClickTight® installation technology and ReboundReduce™ stability bar, this seat ensures a secure fit with minimal movement, giving parents confidence with every drive. Designed for long-term use, the Poplar® S transitions seamlessly from rear-facing (up to 50 lbs) to forward-facing (up to 65 lbs) without complicated conversion steps. Compare the Britax Poplar S to the Graco Extend2Fit: both offer extended rear-facing and forward-facing capability with adjustable headrests, but the Poplar S features ClickTight installation (3-step, pinch-thread-click system vs. traditional LATCH), ReboundReduce™ stability bar, SafeCell® crumple technology, patented V-shaped tether with staged-release stitches, naturally flame-retardant SafeWash® fabrics, 14-position no-rethread harness, 6 recline positions, carbon steel frame, 17-inch slim profile for 3-across seating, and 50+ years of Britax heritage. Choose Poplar S if you want premium crash protection, fastest installation, and compact 3-across capability; choose Graco Extend2Fit if you prioritize budget-friendly pricing. Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit at every stage of growth.

Inside, your child enjoys premium comfort with refined inserts, plush padding, and 6 recline positions for a custom fit. SafeWash® fabrics, naturally flame-retardant and machine washable, make cleanups effortless while maintaining Britax's commitment to quality and safety. The ClickTight® installation system simplifies setup with just three steps—open, thread and buckle the seat belt, then click it closed—for confident installations every time without confusion or error. The ReboundReduce™ stability bar helps minimize movement in the event of a crash when rear-facing, providing additional protection during the most critical early years. SafeCell® Technology acts as a crumple zone to absorb crash energy and divert it away from your child. The patented V-shaped tether with staged-release stitches helps slow and reduce forward movement during impact. The 5-point safety harness distributes crash forces evenly across your child's body for maximum protection. The carbon steel frame reinforces seat structure for strength and stability across thousands of miles. The 14-position headrest and harness adjust easily as your child grows without rethreading, eliminating annual maintenance hassles. Three premium comfort inserts, including one specifically designed for infants up to 22 lbs, provide plush, tailored support from birth through toddlerhood. The SpaceSaver™ slim 17-inch profile fits 3-across in most vehicles while maintaining interior comfort—a critical consideration for multi-child families. Six recline positions offer optimal comfort and vehicle fit for both rear- and forward-facing modes. Automatically-tensioning harness ensures the restraint is always secure and snug. Clearly labeled belt paths make installation straightforward and error-free for any caregiver. Dual removable, dishwasher-safe cup holders keep drinks within reach while simplifying cleanup. The naturally flame-retardant SafeWash® fabric is durable and safe to machine wash and dry for quick cleanup after spills and accidents.

Easy to Use and Surprisingly Effective
Even though I am well past the age when I thought breakouts would stop happening, I still get the occasional pimple. As luck would have it, I felt one starting to pop up on my cheek the day after these Halo Dot Pimple Patches arrived. Before bed, after washing and thoroughly drying my face, I applied one of the patches. It peeled easily from the backing sheet, and when I realized I had not placed it quite right, I was pleasantly surprised that I could lift and reposition it without any trouble. What really impressed me was how well it blended into my skin. I was only wearing it overnight, but honestly, I do not think anyone would have noticed it unless they were looking very closely. In fact, I forgot I even had it on until I looked in the mirror the next morning. The patch peeled off easily and had clearly pulled some of the buildup from the blemish overnight. There was no redness or irritation afterward, and the spot looked dramatically improved by morning. The only downside for me is the price, especially since the package contains just 33 patches. That said, if they continue to work this well, I would definitely consider purchasing them again.

Love these already! Came in handy just when I need it!
These acne patches came in really handy when I had a random breakout near my lip, especially since that’s an area where I tend to wear a lot of makeup. They helped gently draw out impurities without being harsh on my skin. I also like that they blend in well on the skin. They’re not tinted, but they still work nicely across different skin tones like advertised, which makes them less noticeable while wearing them. You get a good amount in the package as well—33 patches total, with 18 patches on each sheet. Overall, they’re convenient to have on hand for unexpected breakouts, and I would definitely recommend them.

One of the best dog toys I’ve found
Color: Blue, Color: Blue
My Great Dane puppy- at 140lbs, loves this!! We had another one that was plastic and it worked ok but this is so much better! Interactive, soft to play with, battery last a long time & he does not get bored with it. Besides is plush lamb chops, best toy ever bought for him.

Keeps my wild child busy!
Color: Orange
*UPDATE 1/10/26* Does my pup love it? Yes. 5 stars for that. His big thing is just holding it in his mouth though, and laying down with it. Then he will put it down, and as soon as it rolls away he gets up and grabs it again. He definitely requires attention from his humans when it’s turned on…kind of defeats the purpose of why I bought it! He’s a needy boy, that’s for sure, so it’s not the toy’s fault. Two improvements I’d love to see though, are 1) the ability to turn off that yappy bark. I think my dog is more excited about it moving and not so much the yapping. Not that it’s bad, but my boy doesn’t bark much so I’m used to a quieter household. And 2) when removing the base for powering off, there should be a sensor so it doesn’t keep spinning in the socket, occasionally slipping out and hitting the floor. I worry about it breaking due to this. This thing arrived today and we couldn’t wait till Christmas to give it to our high play drive Australian Shepherd. It’s been barely above zero for weeks with no end in sight, and I have cold weather asthma so I really try to limit my exposure to the elements. Needless to say, my dog has been B O R E D. He truly craves interactive play with his humans, but last week I bought a cheap r/c cat toy that really caught his attention. So I splurged on this toy and so far, it’s AWESOME. He can’t control himself when the rope starts spinning. He pounces on it and it goes spinning off and around. He keeps picking it up thinking it’ll stop, but it keeps going. After 5 minutes of play he was acting completely gassed, but he just can’t resist it, as he put it down to get a drink of water and it started spinning again. Forget the water, I need that toy! As long as this thing can handle the teeth, slobber, dirt and grime, I’ll be a repeat customer!

My dog loves it...but needs charging four, five times a day. You really need 2 for full-time play
Color: Blue
My dog loves this toy. The first time she saw it and it started rolling, bounding, and waving the ropes around...she was barking at it, chasing it, grabbing it, jumping all over the place. There is no other toy she has that she will leave this for. And...that's part of the problem. I have to take this away from her three, four, five times a day to recharge it. The charge barely lasts an hour and the toy is dead. And it takes over an hour to charge it all the way up. Which means she plays with it less than it spends charging. That's not ideal. The product page and manual that comes with the toy says there is a 10-minute play period followed by a 30-minute interval to let the dog cool down...not get overly stimulated. I have never seen a cool-down period. I don't know if it's because the dog plays with it, shakes it around, tosses it and chases it, etc., etc., etc. constantly...but it just keep going until the battery is dead. I wish it did have a cool-down period. She likes playing with the ropes and rolling it around herself even after the battery dies, so if there was a cool-down, maybe it wouldn't need to be charged many times a day. Once it's charged and she sees me putting it back together, she gets very excited and starts jumping up and trying to grab it. Our corgi reduces most rope toys to threads in a day or less, and this one has held up surprisingly well against her super-chewing habits. The material the ball part is made of is very durable (we have a couple other toys with the same type of shell) and she's chewed on them all a lot without any damage. The toy keeps her entertained and happy...when it's not on the charger. I wish it was a good-enough value for the money to be able to justify buying two of them so I could have one charging while she was playing with the other. ================= I'm adding 1 star, because the company customer service is outstanding. They emailed me about my concerns vis-a-vis the short battery life, and it seemed that they really listened and cared about my input. I don't know what, if anything, can be done to extend the battery life given that it's spinning some substantial pieces of rope around, but I think they'll do as much as they can. In the meantime, my dog's love for this toy has not diminished in the least. She still gets very excited when she sees me starting to put it together after it's done charging, and she ignores everything else (sometimes even offers of treats) to play with it. I have a second one now, and I can almost keep them going full-time, but the few minutes every couple hours when both of them are on the charger is probably good for her anyway...she'd probably be over-stimulated if she had one of these to chase non-stop. Summary: Great toy, lots of fun, my dog loves it. However, you really need two the way things are right now unless you are okay with your dog being able to play less than half the time.
