What Is SensorSafe?

The SensorSafe 2.0 chest clip monitors your child’s well-being, sending timely alerts directly to the caregiver’s smartphone if unsafe conditions arise. Originally developed to reduce incidents of children left unattended in vehicles, SensorSafe notifies caregivers if the car is switched off with a child still buckled, if the child unbuckles themselves mid-drive, if the back seat temperature reaches an uncomfortable level, or if a break is needed due to extended seating time. The alert system extends to emergency contacts with GPS coordinates if necessary, ensuring a continuous line of protection.

Smaller, ergonomic, lightweight, VERY quiet and soft click
Color: Grey
I'm about a month into using this mouse, and so far it checks every box besides being rechargeable. in other words, I preferred battery operated ones as I have no way to use this while its plugged in unless I reroute my whole PC setup just to be able to have access to a USB C cable. I purchased a second mouse for backup. Anyway, its a great mouse, thats extremely lightweight and responsive. the button click is EXTREMELY light, which I love, (similar to a new model macbook pro touchpad click, possibly even lighter) and the overall feel is ergonomic/small which i prefer, since I like to be able to move the mouse around with my fingers rather than my wrist. I use it for my main home PC while using my DAW for music production. The DPI feature is cool I suppose, but I don't really need a quick-access setting to change mouse responsiveness on the fly. My only gripes are two; that I wish the side thumb buttons were moved back toward the wrist a bit more. I can only effectively reach the rear button with my thumb, but the forward button requires me to shift my hand around the mouse each time to click it. Its actually easier to slide my index finger off to the side and press that button if I need to which is weird. My second gripe is the charging: I used it for the whole month (8+hours a day work) and I needed to charge it by the end of the month. Which is not bad, but nowhere near the 6+ months of battery life using a single AA. It does not have an energy saving feature similar to mice I've used in the past (click to wake up), also the little battery indicator doesn't make sense. It only goes off when theres no connection to a PC i.e the PC is turned off. It did not indicate when the battery was low, charged, or charging. I plugged the mouse in when it finally died (which was unforgiving, its not like it died, and I could pop the battery in then out to pause a game, or stop music playing, etc.) and it was underneath the clickers that illuminated red (im assuming that was charging, since instructions weren't clear) and then it was green at some point. Simple enough to figure out, but strange that the battery indicator itself didn't function that way it was supposed to. Charging was fairly quick ~an hour or so? We'll see how it fairs in the long run. Overall, Im happy with this mouse in the short term

Super Nice Mouse for the Price
Color: Grey
I've been using this mouse as my primary mouse for 3 months now. I bought it as a backup for a more expensive mouse that was showing its age but I like this one SO well, I've kept using it. In my opinion, it has a nice feel and works very well. It's lightweight, glides smoothly, is responsive and quiet, and the battery lasts at least a month with several hours a day of use. Connectivity has been seamless. I did download some third-party software to increase the functionality of the side button. Just be aware that if you like a larger, heavier mouse, this one may feel cheap to you. But I really like it a lot.

Marvelous, Versatile Mouse
Color: Grey
I was torn between getting a wireless or a Bluetooth mouse, but this product eliminated the dilemma altogether. It paired painlessly with my MacBook and synced seamlessly with the wireless dongle plugged into my Windows machine. No noticeable lag, but I did not test with games. The mouse feels comfortable in my hand and has just the right amount of heft so that it doesn't feel like a cheap dollar store mouse. The feel of it rivals my more expensive Logitech mouses. Buttons are extremely quiet and provide satisfying tactile feedback. But I think the clincher is all the thoughtful details. I love that I can stash the dongle inside the mouse via a slot on the bottom. The switch to toggle between Bluetooth and wireless, or to shut off the mouse in order to preserve power, is a nice touch. And the recharge capability is as advertised. So far I've been using the mouse for two weeks straight and don't foresee it dying anytime soon. And if it does, it's nice to know I don't need to worry about batteries. Overall, this is the perfect portable mouse to stash in my laptop bag and break out in just about any situation.

Very natural to use in hand. Easy setup.
Color: Lavender
I love this mouse! I wear a size small in women's gloves (USA). This fits perfectly in my hand. The shape is so natural and restful. The color a is a clear pastel purple, a lilac, but not too bright or overly soft. It is a little darker than my screen showed, as the picture appears to have a bright light and reflections. Connectivity has been a breeze. No issues at all connecting to a Surface Pro 11. We'll see how it goes connecting to the 12 ... Doesn't fit in the Smatree brand hard carrying case for laptops...too tall. But I am keeping it for home use anyway. Eve I though I have one of those surface pro lays flat mice coming. Only time I needed a mousepad was one time when I tried to use it outside of my picnic table and there seemed to be little grit so I had to clean that off, and just I have a really loose really thin picnic table cover for the winter that I hadn't taken off yet and it did not like that. But it went on my tablecloth and my kitchen table. It worked on my kitchen counter. It worked on my office desk and it also worked on a mouse pad. I have only used it for about 3 days. Sometimes I would remember to turn it off when I wasn't using it and overnight. Sometimes I didn't. Haven't had to recharge it yet. Update: returned the refurb 11 and bought a new 12. my surface pro mouse came in. I paired it, used it for about fifteen minutes. turned it off. and paired this one. I had to cycle it through since it had been previously paired. This was no trouble at all and only a minute to do. it's too tall for some pockets, but my hand stopped hurting, so I'm going to try to use a separate storage case for accessories. it's radius for moving across the screen is helpfully small.

Great general purpose, inexpensive mouse.
Color: Grey
For the price, it’s an outstanding mouse. Have only used Bluetooth mode, and only used it for basic computer operations (not gaming), but feels responsive and comfortable. Great battery life.
