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!

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!

Out of the box the Quick Start Guide is the best I have ever seen or used! The Owner's manual too was really beneficial and easy to understand. Even though this states 1.0 size, the capacity is similar to larger sizes because no turn table is needed. Like all cooking appliances there is a little fine tuning depending on the need, but this Microwave Oven Cooks as good as it Looks!!!

Best microwave i have owned.

I have had many microwaves over the last two years since it is my primary source of cooking at the moment. This would happen to be the best microwave I have used yet. For starters it is in my opinion the quietest with just the sound of a fan and not that loud hum you would be used to. The sensor reheat actually works. With a plate of leftovers with multiple items it will heat it evenly with no cold spots or over heating.The beverage button heats water for tea to the perfect temp. The pull down door is great. By not having the turntable it is super easy to clean and does have the removable tray that catches anything that might fall down the gap in the door that keeps crumps and stuff off the counter top.
I would recommend this to a friend!

Hi! Thank you for the thoughtful and detailed review. It’s great to hear how well the microwave fits into your daily cooking routine, especially that the quiet operation and even heating stand out compared to others you’ve used. We’re glad the sensor reheat and beverage functions are delivering consistent, reliable results, and that the pull‑down door and turntable‑free design make cleaning easier. It’s rewarding to know these design choices are making a real difference in everyday use.
