The latest car seat in our successful Sirona line is the most comfortable yet: the Sirona Gi i-Size. Extended rear-facing for safer travel up 20kg, this car seat also features integrated Linear Side-impact Protection for defense from all directions.

A range of innovative features also upgrade your child’s comfort, including 360° rotation in any recline position with the easy rotation handle, for smooth on and off boarding. Innovative all-round air ventilation means the ride stays cool, and you have the option of choosing mesh fabrics for maximum breathability with the Plus fabric version.

Five recline positions are available in either direction ‒ tailored comfort for your child, whether they’re a tiny newborn or a fully-grown four-year-old (newborn inlay accessory sold separately). 360° of comfort and safety for their first four years: the Sirona Gi i-Size.

Features:

Up To 50% Higher Safety Levels*

Extended rear-facing – one of the safest ways to travel in a car seat. In the critical first moments of a frontal impact, the child’s body is pushed against the padded car seat shell. This keeps movement to a minimum and reduces force acting on the child’s neck. Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for your child to sit comfortably rear-facing until they weigh 20 kg.

*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.

Quick And Easy Onboarding

A stress-free start to your journey. Just swivel the car seat using the easy rotation handle to face the car door and get your child onboard, in any recline position. You can avoid back strain, while your child stays comfortable in the recline position that fits them, whether they’re a newborn or a toddler. Switching from rear to forward-facing travel is just as easy.

Optimal Breathability

The all-round air ventilation of Sirona Gi i-Size allows air to flow through ventilation channels within the car seat, carrying away heat and helping avoid a hot and sweaty ride for your little one. Choosing the mesh fabric available on the Plus version increases airflow even more – with up to 6 times more breathability than comparable car seat fabrics. The clear choice for comfort in any season.

Easy Onboarding

When you’re getting your child strapped into the car seat, you need all the help you can get. The Sirona Gi i-Size features ingenious loops designed to keep the harness out of the way as you get your child onboard.

Grows With Your Child Up To 4 Years Old

As your baby grows, adjust the Sirona Gi i-Size headrest for a comfortable fit at every stage. 12 positions allow a tailored fit to your child, with the harness lengthening automatically with each adjustment. And it can be adjusted with one hand for extra ease of use.

Side-protection

The Linear Side-impact Protection defends your child against the force of a side impact. Working together with the energy-absorbing shell, the L.S.P. System significantly reduces the effect of impact force on the child.

Always In A Comfortable Position

For every moment, whether your little one is a newborn or a growing child, the ideal recline setting is available in both riding directions – and in the boarding position, too. And when your child falls asleep in the seat, you can recline it with one hand, letting them dream that little bit longer.

Straightforward Installation

It only takes moments to set up your Sirona Gi i-Size. Use an ergonomic handle to click the ISOFIX into the vehicle seat and extend the load leg down to the car floor. Both provide stability and extra safety in the event of an accident. Visual indicators help you confirm the seat is ready to protect.

Right tool for the money
Style: Lawn Edger w/(1) 4.0 Ah Battery
Very impressed with this WORX Cordless Lawn Edger. My driveway have never been edged in over 30 years, this edger handled the job with ease, made a pass at one inch and then two inches. My driveway is 80 feet long, after the two passes I was left with one bar of battery power, great tool for the price. I would definitely recommend this product to any home owner that maintains their own yard.

Cute little bug that does its job. Good value.
Size: 17" (2 x 4.0Ah)
Not bad for the price. Pretty easy to set up (only user stupidity gave me any issues). Worked well for my first cut. Lasted about 32 minutes. I'm gonna give the batteries a more significant charge and try again, though I did charge for over 12 hours and the lights were solid green. So not sure what's going on there. I don't understand how "user technique" applies here, though I did hit a lot of hidden sticks. Could have burned through more energy? Idk. But it did handle those sticks like a champ! I made sure to get all the big ones out of the way, but there were some small ones and it just ran em right over good as any gas mower. I would probably play pickup sticks a little longer beforehand next time, but I was a little pressed for energy today. Anyways, irrespective of the actual function of the machine, I prefer this dramatically over either wider or self-propelled models. Self-propulsion can be very annoying when trying to get around difficult terrain or obstacles. I also enjoy the exercise! The small form factor is very nice again for obstacles or weaving between objects. It also is nice and light and easy to push. After 30+ minutes of mowing I'm not even remotely sore. I also enjoyed just getting to smell the fresh cut grass rather than belching gas smoke! I'm looking forward to low maintenance on this lil guy. The blades seem pretty well made, and I will be keeping an eye on them for wear and tear. I had a nice day outside in perfect weather with this little bug, and can recommend it if you're specifically looking for a smaller mower that lasts 30-40 mins on a charge and can deal with a push mower.

Powerful, easy to use, and perfect for small yards.
Size: 17" (2 x 4.0Ah)
I was pleasantly surprised at just how well this mower cuts and handles! Years ago I bought a Greenworks electric mower and loved it, but it was a pain trying to pull the cord around. When I happened upon this mower, I thought I'd give it a try and am so glad I did! The box is heavy, but this 63 year old woman managed to get it inside the garage and out of the box. The handle is simple to install, as is the grass catcher. The height adjustment mechanism is one of the easiest I've ever used. Once the batteries were fully charged, (they do take a few hours), I had my small front yard mowed in less than fifteen minutes. It isn't as quiet as an electric, but it's not as loud as a gas powered and there are NO fumes. I used the grass catcher and when I emptied it I found that the grass mulched was almost like saw dust! I hope this machine lasts a long time!

Good little mower but not perfect
Size: 17" (2 x 4.0Ah), Size: 17" (2 x 4.0Ah)
Decent little mower. Purchased it so I could take the sketchyness out of my front yard using my rider with the slope I have. Did a good job cutting the grass and is super quiet and very light weight. I've added some pictures of the handle extended and folded down next to my other tools for some size comparison as well. Stores well too. Grey button circled is how you adjust the deck height. Press and lift or push while holding the button down until you get your desired height and release. Super easy. Battery life is ok. I wouldn't be able to do my entire yard front and back on one charge. Batteries were almost dead after what felt like 25 minutes of use but my grass is rather thick so theres that. It did what I wanted it to do on one charge so I'm happy although it won't do a full yard front and back. You would need an extra set of batteries for that. Little assembly required. You have to put the grab bar on and install the mulch plug or bag yourself and charge the batteries before use and you're good to go. Not a super strong mower but thats to be expected at the price point. Strong enough to get the job done though. Some of the thicker parts I had to do two passes to get a good cut and it stalled out on me once. Thats ok though because I have the mulch plug installed and mulching boggs down any mower. 4 stars because there isn't a good carry handle to use when it is folded up that I could find. You kind of have to manhandle the thing into where you want once its folded up. Opened the box when it got delivered to find the batteries and charger just tossed in by the factory. Was a bit frustrated seeing that stuff just banging around in the box. Pros Quiet, light weight, stores great decently strong Cons No go handle when folded up, packaging Would I recommend? Yes. Good cheap alternative if you have a very small yard or are needing something to edge with or need to get to a hard spot that a rider is not the best for. Plus you don't have to worry about a cheap gas mower blowing your arm out with 10 minutes of pull starting.
