The CYBEX Sirona S is the ONLY Convertible car seat to feature a 360 rotatable seat with load leg stability, linear side impact protection and SensorSafe technology. With a 10Year Expiry!
The CYBEX Sirona S is the first Convertible Car Seat in North America to feature an innovative 360° rotatable seat with a load leg, making switching between rear-facing and forward-facing positions quick and easy. The Sirona S load leg stabilizes the seat and can significantly reduce crash forces.

Built into the chest clip of CYBEX car seats, SensorSafe provides alerts when unsafe situations arise including if a child unbuckles themselves; if the back seat has become too warm or too cold, if a child has been seated for too long, and if the driver accidentally leaves the child behind.

Shape can be a game changer to reduce arm/wrist pain
Style: Right-Handed, Pattern Name: Mouse, Color: Graphite
Very easy to setup with PC, whether by bluetooth, usb, wifi. It does take some time to get used to the new design. The scrolling is very good and all functions are extremely responsive. So far, it is not causing any strain to my arm and wrist which is why I am trying this design as my older, normal shaped mouse, was causing me arm pain. They should include a quick easy to understand information sheet about the buttons. Need to download in order to customize 2 other buttons. All in all, so far I like it and definitely suggest it for people having arm or wrist pain from the angle and position of a regular shaped mouse.

Wonderful!!
Style: Right-Handed, Pattern Name: Mouse, Color: Graphite
Update -
After using this mouse for over a year I started experiencing something profoundly annoying. When dragging something from one place to another (often from monitor to monitor) I would accidentally hit one of the buttons by the thumb and it would close whatever I was working on. Especially during work where I do this often. I found there is an option to turn these buttons off in the software!!! Wonderful!!!
That was the absolute only thing I was having an issue with. Longevity has been perfect and I'll confess, I'm not particularly regular about cleaning it. I would buy this mouse again in a heartbeat.
I bought this at the same time (Feb '25) as the Logitech Ergo K860 Wireless Ergonomic Keyboard - Split Keyboard, for which I have also written a review.
I cannot say enough good things about both of these products. My neck, shoulders and back feel so much better than with my previous setup.
At the time of purchase, there were a number of reviews saying these failed fairly quickly. This has not been my experience and I am not very conscientious about cleaning it.
After almost a year of heavy use (8-10 hrs a day), the batteries are at 30% which I don't think I can complain about.
These products are not cheap, but for me they have been worth every penny and I cannot see myself going back. I'd buy them again in a heartbeat.

Easy setup, beautiful red!
Color: Red, Color: Red
I needed a mouse for an assignment when I asked my son for his. I loved it so much that I needed to buy myself one. I bought the red to match my computer (and to know that the navy blue is my son's) and it's a very sleek, not tooo vibrant color. It does come with both an USB & USBC controller (see pictures) and mine connected FAST to my computer. It does NOT come with a battery (most mice won't) so please grab a DOUBLE AA battery before it comes in so you will be ready. I have no issues with the mouse and loved the price point on this one. It's light weight and easy to setup. Then again it was a plug in/play setup, so if you're not tech savvy, you won't have issues with this one. Just choose a color and get it!

Cut the Cord and Never Looked Back!
Color: Grey
I'd been using a wired mouse forever and kept telling myself the cord wasn't that annoying. Spoiler: it was. The moment I switched to the WisFox 2.4G Wireless Mouse, I realized what I'd been putting up with all along — and there's no going back now.
Setup was dead simple. Plug the little USB receiver into the laptop, and it just works. No drivers to hunt down, no pairing headaches, no nonsense. The 2.4G connection is solid and responsive — I haven't noticed any lag or signal dropout, even when the receiver is tucked into a port on the back of the laptop. The cursor tracks smoothly across my desk surface without any skipping or stuttering.
The ergonomic shape is a genuine plus. It fits naturally in the hand during long sessions and doesn't leave my wrist feeling fatigued the way some flatter mice do. The buttons have a satisfying, tactile click without being loud enough to bother anyone nearby.
My one gripe — and it's pretty minor — is that it runs on batteries, which means you'll eventually need to swap them out. It's not a dealbreaker by any stretch, and the battery life has been reasonable so far, but if you're used to a wired mouse that just runs forever, it's a small adjustment to keep a spare AA or two around.
Pros:
Instant plug-and-play setup with the USB receiver
Reliable, lag-free 2.4G connection
Comfortable ergonomic shape for extended use
Great freedom of movement without cord clutter
Cons:
Runs on batteries — plan to keep a spare on hand
If you're still tethered to a wired mouse and on the fence about making the jump, this is a solid, no-fuss way to do it. Hope this helps!
