1 out of 1 found this review helpfulThis 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.oneLarry A. from Park Falls Variety Store on 11/27/2018

1 out of 1 found this review helpfulThis 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.Matt B. from MAD meal preps on 05/06/2017

1 out of 1 found this review helpfulA 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.Amber G. from Violette's fine pastries on 10/29/2015

This oven, like many of the reviews, only lasted a year. It sparked, tripped my breaker and shut off. When we did get it to come back on, it would no longer heat. Even with COVID, the lack of business, and some business closures, when I contacted webstaurant store to resolve my issue, it was 10 days over a year so my warranty wasn’t any good. I was given the option to purchase repair parts or a new one. I have purchased many many things for my restaurant, however this was the most disappointing purchase and it has definitely left a bad taste in my mouth.Salvatore i. from Sal & Judy’s Restaurant on 03/04/2021We appreciate your review, Salvatore.

Unfortunately you get what you pay for. This is my second Avantco CO-28 oven in a year. Bought the first one on January 11th, 2020 and the second on August 15th 2020. Both with the same problem, fan works well but the heating element burned.Jose C. from Blends on 02/15/2021We appreciate your review, Jose.

Not worth the price tag, will die like clockwork once it's outside of the year warranty period. I didn't heed others' advice and I paid the price for it. Since we were closed for COVID, we only used the oven for 5 months before the heating element died, but since the purchase date was over a year ago, customer service refused to do anything about it.Whitney L. from Meeples Cafe on 11/22/2020Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.WebstaurantStore Customer Solutions

You definitely get what you pay for. Mine is cooking unevenly, it has major hot spots, and even though it's convection you need to rotate pans to get uniform cooking. It runs low on temperature and the temperature dial is worthless, you will need an oven thermometer. And finally, you can only use one rack at a time. If you use more than one, whatever you put on the other racks will be either undercooked or overcooked.Jose P. from Home Use on 07/29/2020Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.WebstaurantStore Customer Solutions

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.Jessica J. from Icki Sticki on 05/01/2020

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.Herman H. from In-stock supply inc on 04/14/2020

Not built to last. Within the first 6 months the door failed and was replaced under warranty. We bought this oven in Oct 2018 and it officially died March 9th 2020, just over a year so it's out of warranty. It worked ok while we had it, it had hot and cold spots so the pans had to be rotated for even cooking. When it finally died it melted the breaker and flipped a bunch of other breakers, which happened during service of course. If you decide to go with this oven just know you will be replacing it.Andrew P. from Pamplona Tapas Bar and Restaurant on 03/10/2020Thank you for your feedback!

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.Diana S. on 01/28/2020Thank you for your feedback! We are sorry your Avantco CO-28 Half Size Countertop Convection Oven, 2.3 Cu.

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.Robert H. from Harbor House Seafood on 01/20/2020
-
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.Jennifer L. from Jennifer Lee's Bakery on 01/03/2020
-
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.Troy P. from Fit Baking Company on 11/25/2019
-
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.Caroline C. from Jefferson Country Store on 09/26/2019
-
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.Alanna D. from Alanna on 08/05/2019

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

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.Ian M. from Little Lion Ice Cream on 03/29/2019

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 C. on 10/01/2018

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.Molly M. on 08/31/2017
-
one of the best ovens ive used...bakes evenly and efficiently...the fan blows hot air so all my cakes and pastries bake up more fluffy and light!Feraz A. from home on 01/22/2017
-
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.Katherine S. on 01/06/2017
