I’ve been using this microwave for a few weeks now, and couldn’t be happier with this purchase. Yes, it cost more than other microwaves, but in my opinion the benefits of the smart sensors and spacious interior is worth it. It defrosts and/or reheats to perfection, with just the push of a button. The door opens downwards (like an oven), which gives more elbow room, especially if the microwave is placed in a corner space.
I would recommend this to a friend!

great overall - any way to change the default temp

Excellent hearing and function but the default setting for auto reheat is a bit too hot. It seems the target temperature is 75C to 80C. I prefer closer to 60C to 65C. I know you can adjust the temperature immediately after starting auto reheat by turning the dial, but is there anyway to change the default temperature from 4 to 3?
I would recommend this to a friend!

Honestly obsessed with this microwave. It looks so good on my countertop that everyone who comes over asks about it! And it actually works great, food comes out evenly heated, hot inside and out, no drying, no cutting stuff in half to warm the middle. Love it.
I would recommend this to a friend!

Different from all microwaves, and better in many ways. Gone is the glass tray and turntable. The door opens down from the top like a real oven, which may be good or bad depending on your counter layout, (I like it). The controls are not intuitive, so be sure to look that manual over first. The thing I like about this oven the most is the ability to make it not beep. It is very quiet except for the fan. The thing I’m not wild about is the fan. I runs for a few minutes after every cook job.

Hi there! Thank you for the thoughtful 4-star review. We’re glad to hear the oven’s design, quiet operation, and features like the no-beep option stood out in a positive way. We also appreciate your balanced comments about the control layout and cooling fan, as insights like these are very helpful and give a clear picture of the everyday experience.

Moisture Moisture Everywhere...

First let me say that I love the design and concepts behind this microwave. It is aesthetically beautiful. I was excited to get it because my space didn't allow for the standard right swing door that every other microwave uses without significant rearranging of my space.
Unfortunately, the issue I am having is moisture. I used the unit twice. After the second use, which was to reheat rice, the condensation build up was noticeable on the door window. This typically happens with microwaves immediately after use. No biggie.
The next evening, over 24 hours later I noticed the condensation didn't evaporate. I opened the door and noticed droplets on the edge of the interior of the unit, then more droplets all along the back of the unit. 36 hours after the last use it was still there. This is seriously concerning for 3 reasons -
1) Potential for rust to start.
2) Lack of venting allows mold and mildew to build up, which is problematic around food.
3) It is an electrical unit - which accumulation of moisture can create a fire hazard.

After just 48 hours of having it, I opted to return.
No, I would not recommend this to a friend.

Hi there! Thank you for sharing your experience. We’re glad you liked the design and the left-swing door concept, but we’re sorry to hear about the persistent condensation you noticed after use. Your concerns about long-lasting moisture, especially the potential for rust, mold/mildew, and overall safety, are completely understandable. We appreciate you outlining what happened so clearly, and we’re sorry this led you to return the unit.

I absolutely love this microwave! It’s quiet, easy to use, and has a sleek, modern look. But the biggest win for me was how it reheats food—especially sandwiches.
I reheated a sandwich and it warmed the inside perfectly without making the bread hard or chewy, even after sitting for a bit. That’s been a constant struggle for me, and this microwave completely solved it.
Total game changer for my family—I’ve finally found the perfect way to reheat hot sandwiches!

Highly Recommend! Great Quality!

I have been using this microwave for 2 weeks now and I'm very pleased with my purchase.
GENIUS REHEAT SENSOR - The Genius Sensor is Excellent! I am a busy mom and appreciate when an appliance saves me time. It reheated baked chicken, turkey breast, salmon, potatoes, rice and vegetables, evenly. I was pleasantly surprised, especially because the chicken and turkey were refrigerated. This Sensor takes the guess work out of reheating leftovers.
POPCORN - We made Popcorn in a bag and it popped all but 3 kernels, which is impressive considering that anyone who has popped Popcorn in a bag knows that you always wind up with many un-popped kernels and if you try to pop the bag for longer, you wind up with burnt kernels.
BEVERAGE - The beverage button is very convenient. We heated milk, coffee and tea with no issues.
Overall, I'm very pleased with my purchase. This microwave is a great addition to any kitchen. I highly recommend it!
