How SensorSafe Works
Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to act quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive. For ease, just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind.
Features- Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
- Alerts through the caregiver’s cell phone if the child is left behind in the vehicle secured in the car seat and then alerts the designated emergency contact if the situation is still not remedied
- Emergency contact receives GPS coordinates of the vehicle’s last known position
- Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled their chest clip while the vehicle is in motion
- Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
- Provides warnings to the caregiver when the child may have been seated for too long and needs a break
- Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
- Only one install needed if receiver is kept plugged into vehicle’s OBD port
- Helps ensure proper use by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the SensorSafe app
- App can monitor up to 16 chest clips on a single platform
- App download available for Android and IOS

Cheap but must babysit your food (TL;DR: spend a bit more for a better one)
Size: Medium Capacity
I have the “Medium” size of this and have now had it for a year and a half. It basically does what a toaster/convection oven is supposed to do, but I do keep encountering issues with burning food. There is very little space between the coils and the rack so even thin things like slices of bread are very close to the heating elements. As there is no way to only use the lower coil, any toasting or cooking requires preheating so the coils aren’t all at full capacity for 5+ minutes. If you essentially preheat it, you can then toast or cook, but keep a close eye on it as even with preheating, you may need to turn and flip what you’re toasting every 30-90 seconds or the section under the coils will burn while the rest remains pale. When you’re making toast, it’s a lot of effort and practice to get your bagel or toast just right. As there is very little space and the elements are intense, even if you force the rack below where it’s meant to go (you can kind of wedge it between the guide and the bottom heating element cover), you can only fit things that are about 2-3” tall and those may still be a challenge. If you want to put a fairly tall piece of frozen lasagne in, for instance, the top will burn to a crisp before the center is even thawed. I’ve never had issues like these with previous toaster ovens, even small ones. I think they really did everyone a disservice by not making it about an inch or two taller inside.
I also find it extremely challenging to clean. I’ve had many toaster ovens over the years and none have stained and discolored this easily. It’s an issue partly because of the small size inside, so you can’t reach everywhere, but even the glass door has gotten stains I cannot remove despite trying everything from lemon juice and baking soda to Ajax and Bar Keeper’s Friend.
Overall, can you find ways to make it work as long as what you’re cooking is short? Yes. Is it convenient or ideal or a great toaster or toaster/convection oven? No.
Update: About a month after I reviewed this, it caught on fire. I had about a teaspoon of oil on a baking sheet and when I flipped the piece of chicken halfway through time, a tiny bit splattered and because the top coils are right there, it burst into flames. I know enough to close the door and unplug immediately so it burned itself out. Now, the fact that oil splattered a bit is my carelessness, but as I said, it was only a teaspoon of oil so it’s not like it was being deep fried, and I have done the same thing with every toaster oven I’ve owned and never had that happen, because the coils shouldn’t be so darned close that they touch the food. So that was it for me. I spent about $25 more for a Hamilton Beach Easy Reach that I LOVE. It has enough space, doesn’t take up much counter space, and is a breeze to keep clean. I wish I had just spent a little more the first time and gone with what I have now. Save yourself my mistake and a toaster oven ending up in a landfill and spend the extra $$ to get one that works better and is safer. My parents have the older model of what I now own and have had it for over a decade, using it at least once a day, often twice a day.

Works well.
Size: Medium Capacity
Air fryer and toaster work very well (Thats all I tried so far.). About 2 medium potatoes sliced into wedges fit in tray. The top and bottom get very hot. Will burn if you touch them.

Testing it out
Size: Medium Capacity
ORIGINAL REVIEW, OCT 2025:
So far this little oven is doing great. Right now it's 4 stars but has the potential to change as I use it more often, right now I've only used it a handful of times.
Heats up quickly so there's no growing old while waiting for preheating, a definite plus. The air fry option is super quiet, way more quiet than any air fryer I've ever had. Downside is there is no way to adjust temp for this setting so you really have to keep an eye on the food to see when it's done.
DO NOT USE PARCHMENT PAPER IN THIS OVEN! I made that mistake because I use it in my regular full size oven as well as my old air fryer, but it's not compatible with this oven! I almost started a fire! Good thing I didn't walk away from it.
I like that there's a timer feature so it will shut off, very helpful in times you are in the middle of something else at the same time and this avoids your food getting burnt. There's also a stay on feature in case you prefer that. For the timer you have to make sure you pass the 10 minute mark and then set it to the time you want.
The oven is smaller than I expected. I don't know yet if a pizza will actually fit, I'll update when I attempt it. I've only made English muffin pizzas and French bread pizzas so far.
One thing I really like about this oven is that it tends to cook food evenly. I've had toaster ovens that cook more on one side than the other and more on top than the bottom and it's frustrating! The stuff I've made in this oven were nice and crispy both on top and the bottom and it's so nice to not have pizza that's burnt on top and mushy on the bottom! I'm glad finally a manufacturer figured this out.
This toasts really nice too. Watch the time with this. My bread got toasted way faster than with my old one!
Overall I'm happy with this. I'll update as necessary.
