The Black & Decker CTO4500S is an affordable counter top convection oven that is a good fit for people that want the ability to convection bake, but don’t want to spend a lot of money.  If you’re looking for a good all purpose small oven at a reasonable price, then this could be a good option.  However, this unit is a much better oven than toaster.  Therefore, if toasting is of prime importance, then we recommend the Cuisinart TOB-40. It’s in the same price range, but toasts a lot better.

Features and Specifications

  • 1500 watt toaster oven
  • Dimensions: 20.1″ x 16.3″x 12.6″
  • Convection: Yes
  • Slice capacity: 4 (claims 6, but they would have to be small)
  • Functions: Toast, Broil, Bake, Keep Warm
  • 60 minute timer
  • 2 rack positions
  • Fits a 12 inch pizza (just barely)
  • Slide out crumb tray
  • Non-stick interior
  • Grounded 3 prong plug


The CTO4500S is a good looking toaster oven that has a helpful circular bump in the back of the unit to help accommodate larger size pans and pizzas.  Customers mentioned that the housing appeared to be relatively solid, but that it seemed to be less insulated than other toaster ovens.

Toasting & Cooking

For baking, this model does a fine job and most were quite happy with the results.   Customers reported that the oven cooks fast (due to the convection fan) and does a good job of cooking the food evenly.  Customers did note, however, that the convection fan is somewhat loud.  This shouldn’t be a surprise though as many convection fans -especially lower priced ones – tend to make some noise.  Additionally, customers said to be careful with the cooking times as this is a convection oven so it will cook faster than the usual time given in the recipe.

The broil function also works just as well as the bake function and customers didn’t have any issue with this function.

For toasting, however, there were mixed feelings and reviews.  The overall sentiment felt was that this unit works better as an oven than a toaster.  One of the reasons for this feeling stems from the inconsistency people had with their toast, which comes as a result of how the toast setting is operated.

To toast, you will need to first turn the cooking timer past 20 minutes to initiate the heat and then turn it back down to a lower position.  However, the lowest time indicator is 5 minutes, so you will need to use your best judgment as to where to put the dial.  Therefore, it doesn’t have a fine level of control.

Additionally, customers warned that shouldn’t walk away from the toaster oven while it is toasting because in case you set the timer for too long, the food may catch fire (this actually happened to a couple of people).  Moreover, if you want better toasting results, people said you really need to read the instruction manual as to where to place the rack and the bread and also keep a close eye on the toast because you may need to pull it out earlier than the timed cycle.

All in all, the CTO4500S can make decent toast – you just need to watch the toast carefully and not leave the toaster oven unattended.

Using the CTO4500S

The Black & Decker CTO4500S is a three dial toaster oven.  The first dial controls the oven temperature (up to 450°), with the second dial setting the cooking function (Keep Warm, Bake/Convection, Broil, Toast), and the third dial controlling the timer (up to 60 minutes).

Customers mentioned that the knobs are smooth and that the spring on the timer is tight, so it does require some strength to twist it.  Therefore, children and the elderly, or people with arthritis who don’t have a lot of hand/finger strength, may find using the timer difficult.

The is also one of the easier toaster ovens to clean with it’s non-stick interior and handy slide out crumb tray.


This model comes with a slide out crumb tray, a broil rack, and bake pan/drip tray.   They are not enamel coated, so they are rather flimsy and must be handled delicately.  If not, they can easily get bent.

Customer Wishes & Complaints

As previously noted, customers wished the toast setting was easier to use and toasted better.  This is not a set and forget toaster oven, meaning you can’t just leave it on your perfect toast setting and pop in the toast and hit start. You must watch the toast carefully so that it doesn’t burn.  Also, finding the right spot to place the toast so that it cooks evenly can be a bit tricky.  Even after following the instruction manual, some people found it difficult to get the bread evenly toasted.

Customers also wished the spring for the timer dial was easier to twist.  This one has a powerful spring and takes some strength to turn it.  Additionally, customers wished it were easier to select the time position more precisely.

Some people also said that this toaster oven gets very hot on the outside of the unit.  However, this is a very common toaster oven complaint that can be found with almost all toaster ovens (more so with the lower-end models).

Consumers also wished that the accessories like the baking pan/drip tray and rack were made of better quality.

There were also a couple reports about the glass door shattering, but they were probably isolated instances and not a common characteristic.

Summary of the Black & Decker CTO4500S

If you like to bake and don’t want to have to fire up your wall oven to cook small items, then the Black & Decker CTO4500S may be good for you.  It’s convection fan feature works well and allows you to cook food faster.  It’s also very easy to clean.  The primary drawback, however, is that it is not great for toasting.  The way the timer and the toast function operates makes it difficult to get consistent results.


  • Bakes well with the convection fan
  • Easy to clean with slide out crumb tray and non-stick walls
  • Affordable price


  • Not great for toasting
  • Difficult to use timer
  • Poor quality rack and pan/tray

    This toaster oven is small but meets my expectations. It does a great job toasting baked goods and reheating food.
