Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Countertop microwave

Jeri 77 6/8/2026

Instructions confusing on releasing the child lock feature. Unable to use the clock for time of day when microwave is not in use. Product is not simple to use. Very disappointing

Microwave

Veeto 1/21/2026

Worst microwave I have to owned. Loud like my old 50 years washing machine from day one. Just use cpl days only. I can™€™t stand it. Start looking another brand. GE going down with quality control to fast. I use to love it GE Aplaences but now not anymore. Bought kitchen set cpl years ago. Dishwasher stop working exactly in 3 years after stop warranty and microwave stop working in 38 months. Refrigerator still works thanks got.

Previous one prematurely failed

MadSad 1/7/2026

This is my second purchase of this model. Our last one broke after about 2 years use. Very disappointed. I bought another one ONLY because the size fits our space. Otherwise I would not have purchased another one

Simple and Sleek

LJ2025 9/4/2025

Just what we needed for our pantry. I didn't want anything too big. Definitely not a huge capacity but perfect for your average heat ups.

Just what I was looking for

RaccoonWhisperer 9/1/2025

Outside design is very sleek. Touchscreen, as opposed to microwaves with dials, etc. is easy to clean. The multistage cooking feature is great! I use it everyday for oatmeal. Especially love the timer. Instead of having to access my phone and then go to and set its timer, the microwave timer is handier and it only takes three keystrokes to start it. Perhaps GE would consider adding backlighting to the control panel to make it easier to read. Otherwise, I'm glad my previous, high-end microwave crashed because I like this one better.

Good little microwave with lots of power!

Jojo930 7/31/2025

This microwave is full of surprises, enough room for a 10" plate or a bag of steamed veggies and very powerful for a space saving appliance.

Lacking Aesthetically

RDF49 7/16/2025

I have a black microwave. The key pad is difficult to see unless there is an overhead light on in the kitchen (back lighting the touch pad would be nice). Additionally, though it hasn't created a problem, the door doesn't line up as you would expect. Looks crooked though it does not seem to be a problem sealing the cooking compartment when shut.

Solid smaller countertop microwave

shellb54 7/15/2025

I've had this small countertop microwave for about 4 months and it does a very good job reheating leftovers and cooking fresh and frozen veggies - what I mostly use it for. I don't do complicated cooking with it. It has a decent capacity for being a smaller machine and I haven't missed my larger over the stove one at all. The only thing I would like that it doesn't have are lighted controls. It is a 900W microwave, less than my last larger one, but this hasn't been an issue. Another plus is that it was quite inexpensive at around $120. Definitely would purchase again.

They Make the Best...

GE Microwaves 6/16/2025

GE makes the best small size microwaves! This 900 Watt model gets the food so thoroughly hot much quicker than my old 700 Watt GE The new features for setting up the food to be cooked are much easier to use & are so quick & instant This is the 'Go-To' Microwave & I'm completely satisfied

I replaced with the same unit due to size constraints. The first GE unit did not last poor quality.

CocoaBeach1 4/9/2025

We had a larger microwave prior to this one, with a lot of buttons. This new one, is a perfect size for what we need it for. Plus ease of use is nice.

A Bit Disappointing

Farmer Lady 12/26/2024

Negative: **The door does not fit tight. Thus, it vibrates and makes noise on certain settings. ** Can't seem to make popcorn in my microwave popper without burning a clump in the center. Positive: LOVE, LOVE, LOVE that the sound can be shut-off! No ear piercing beeping. ("Mute" light totally unnecessary??) Also, love that clock display can be shut-off.
