Customer Reviews

We took a full size stove/oven out of a kitchen where we really only needed the oven function, and we now use this countertop unit. It works great for keeping pans warm and also does a great job of cooking multiple pans at once. It's well sealed and sturdy. The top does get warm, so we wouldn't recommend planning to have the top for stacking anything.

This was great, but make sure you have the correct outlet or plan on having some electrical work done. I love the height between racks.

We use this great little oven to hot-hold some of our restaurants menu items. It holds a consistent temperature, heats up quickly and has held up well so far.

Heating not consistent, we are having trouble getting our baked goods to cook evenly with this oven. Have adjusted temp, spacing, turning and cannot seem to make it work for us. Small coffee shop that offers baked goodies so oven is crucial, sadly would not recommend if baking evenly is a priority.

We are a small coffee shop and this oven is the perfect size for our space! It had great reviews and was extremely affordable. We are extremely happy with it so far!

Amazingly consistent! We use this oven all the time in our kitchen. The back top corners get a little hotter than the rest of the unit, so depending on what you put in there you might have to rotate your trays at some point. Once we figured out a system it's been a gem to use.

This was the cheapest, largest counter top convection oven I could find. I didn't have a big budget and needed to make this work. The first thing I noticed while I was baking veggies was the seal between the door and the oven would leak steam and water would start to drip down the front door. I tried fixing the seal but it just doesn't seem to fit properly. The second thing I noticed was the veggies in the back would brown first so I started to rotate the baking sheets 180 degrees halfway through the cooking process and that works wonders. Overall i'm satisfied for the time being, I do plan on replacing this in the future with a larger higher quality oven.

So this item is not my favorite. we ordered it to fit a small space, when picking ovens i prefer a full size, and natural gas, but this unit works in a pinch.

I highly recommend this oven. Pros; It heats up in minutes, and it is inexpensive. Cons; the temp dial is worthless you have to by an oven thermometer, and the timer is only good for 60min.

You get what you pay, Lightweight oven perfect for catering. Mine is cooking unevenly, must rotate pans every 10 min to get uniform cooking. But for less money its ok.

This is a beast! This unit is a work horse. The Avantco CO-28 Half Size Countertop Convection Oven, 2.3 Cu. Ft. - 208/240V, 2800W and also the 110v are great.

We've been using this in our cafe for light baking every day for about a month now, and it's great. I wouldn't start a bakery with it, but for light baking at the beginning of the day it works just fine.

The Avantco CO-28 Half Size Countertop Convection Oven, 2.3 Cu. Ft, came fully assembled and was as easy as plugging it into the wall. The products meets our expectations for a small operation like us

This was such a great buy!! It works good, doesn't get too hot on the outside and has good heat distribution. The price was very reasonable too. Would buy another.one

This fits perfectly in my small space and heats up quickly and is well insulated. Even though it is convection, rotation of the pans is still necessary to keep products from burning on one side.

A perfect sized oven for my boutique bakery, I love the way it fix all of my goods perfectly and evenly, as well as time efficient. A countertop oven is perfect for space saving as well.

Too big. Took up way more space than we needed for our counter convection oven. The smaller one works More prefect for our cookie operation.

Ashley Carlton from

Excellent convection oven for a great price! The oven itself is actually relatively light, so you can move it around, if need be. It's quite and works really nicely, and doesn't take up a ton of space. Perfect for small loads of things that need to get baked. The only slight downside is that the dial is not terribly accurate/easy to read, so you have to eyeball the temperature on the dial, to the best of your ability.

The oven is definitely bigger than I thought. It definitely works really well for cookies. however for bigger items I need to take a shelf out so that there's enough space in between the racks.

First of all the power cord was backward compared the spec sheet. Major hot spots and runs low on temperature. Within two months we decided to get something better, now just need to figure out how to get rid of this one or sell it. As a business owner it’s annoying to spend time on things like this.

This is my second avantco half size countertop oven and I have really enjoyed them. They heat up very fast and very hot so make sure to monitor whatever you are cooking or add a gauge on the rack.
