  • Rated 5 out of 5 by from Great product I absolutely love this microwave. It makes all other microwaves seem outdated. It is super intuitive, very sleek in design and most importantly.... it cooks fantastically. I've yet to make anything that wasnt done or done on the outside but the inside. Great product.

    Rated 5 out of 5 by from Very quiet door I love how quiet the door is! No loud clanging or clicking when shut. I had to double check the first few times to be sure it was shut. While cooking, its silent also. The fan noise is minimal. The preset features are cool. Tried it first to reheat a pasta dish and adjusted automatically to ensure it was completely reheated. It takes some getting used to, but its easy to maneuver. It is also easy to clean and wipe down (but I found I haven't had too much issue with splattering or popping).

    Rated 5 out of 5 by from Amazing This is such an awesome microwave. The technology seems very upgraded and higher quality compared to other microwaves I’ve used. Food heats up evenly and quickly. The microwave itself is extremely sleek and stylish looking in the kitchen. I’ve had guests comment on it that they are loving the design. It is also more quiet than others I’ve had. Highly recommend this. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Microwaving Coffee has never been so easy! I said that I would never be one of those people that Microwaves coffee, but then I had three kids! One of the best parts of this unit are the present buttons to easily warm up beverages (it even give you the option to select how many cups you are warming up), heat up pizza, melt chocolate, perfectly melt butter, etc. It is also very easy to dial in the time and power for the thing you are microwaving. I also like that you can control the loudness of the chime. If you have kids and don't want to wake them with obnoxious noises, this unit can help. Overall this is a very high-end microwave that is easy to use and evenly heats up food. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from smart microwave this is the one i got the Breville The Smooth Wave smart Microwave because i am always looking for the lastest brand and product that comes out especially for my kitchen anything to make cooking easier and faster so who would not want a smart microwave and let me tell you this did not disappoint. I absolutely impressed with its Sensor IQ tech. I was honestly surprised at the versatility of this oven. It comes with several cooking presets including a preset for bacon which get used alot in this house . I love the sleek look of this microwave and not having buttons to push love the two knobs .And i absolutely love that it heats the food evenly no cold spots even when you put something over the food to stop it from splattering all over the inside of the microwave.

    Rated 5 out of 5 by from Superior Quality Breville has done it again! I am astounded with the quality of this microwave. Not only is this visually appealing but the performance is amazing. This is not your normal microwave. Everything I have heated has came out evenly heated. No over cooked areas and no cold areas- just an even heat! When using it to thaw frozen meat again evenly thawed and no areas over heated or cooked! It is very quiet while in use and closing the door is the same. No more slams or bangs!

    Rated 5 out of 5 by from wow! i'm so impressed I'm beyond thrilled to be writing this review. I took some time to test out the features and all I can say is that this is the microwave of your dreams. It's super easy and extremely convenient. the smart technology lets you defrost, reheat with the preset controls. fun, isn't it. you don't have to think how much time it would take to defrost a particular item. take out the guess work and throw it out of the kitchen. next, I like the shortcut buttons. craving popcorns? simply place the bowl with corns and select the preset. voila! popcorns ready in minutes. reheating pizza is no fun but with the smart technology this microwave uses, it evenly reheats the pizza and doesn't make it soggy. It is beautifully made and it has enhanced the look of my kitchen. it's spacious from inside and I have noticed that the dishes don't splutter if they have been kept for a bit longer to be reheated. it's easy to clean and to be honest I have used it a handful times now and not once I have noticed any smell of the previous food in it. I'm extremely impressed with the overall performance, design and energy consumption of this microwave and I highly recommend it. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Better than I hoped for I got this microwave after renovating my kitchen. This microwave is precise, and has a great gentle close door. Its big, but not too big and cooks popcorn perfectly. Something that no other microwave that i have owned has ever done. :) [This review was collected as part of a promotion.]
