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 and 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.

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

Love it! Wish it would sit flush to counter!

Submitted by AlmostEcstatic - 12/13/2021

We finally got our cooktop delivered and installed and the space between the 5 burners is ideal, the position of the dials works so well for avoiding catching them on our hips, and the flames are so far, extremely responsive to the level setting. Only wish it were not slightly warped so that the back corners don't sit flush to the counter! We're balancing heavy pots on the back corners to maybe de-warp it. We'll see how that goes. Might have to ask for a replacement? If they can address it, my review will be an enthusiastic 5 stars!

Looks good, definitely has design flaws

Submitted by jbkat - 9/15/2021

I've had this cooktop for almost a year now and I have to say, at best, it's frustrating. The knobs at the front are difficult to clean with tight corners and too close together to clean in between them. The grates are a horrible design with shorter tines next to longer ones which means that the pots rock on the burner unless they are perfectly placed. The burner sizes are awkward and don't fit my pots. I thought maybe it was my pots but when I used the chart in the user manual and tried to find 2 qt and 3 qt saucepans that would fit the burners, they are all too small. This means that the nice strong flames go up the sides of the pot and not under it. Finally, it is so tricky to get it to light. I have to try over and over again and hold down the clicking ignition for quite a while. That is ridiculuous in this day and age. My 5 year old bbq lights better than that. All in all, this cooktop is frustrating and awkward to use and care for. It's surprising and disappointing.

Still a work in progress

Submitted by Ned H - 9/13/2021

We like the range, but we're still working through a few issues with getting the burners to stay lit when starting - particularly on smaller ones. Once working, things are great. Easy to clean, good heat. Hoping we'll get this resolved.

Excellent improvement over previous Bosch cooktop

Submitted by GregS - 6/1/2021

I installed this cooktop after removing a 15 year old Bosch cooktop that was having problems with ignition. I also wanted the more powerful cooking element for boiling water and the smaller element for simmering, which were not on my other Bosch. Anyway, it was easy to install and has worked perfectly except a thermocouple became faulty so the eye would not stay lit, but a repairman came promplty and replaced it and it has worked great ever since.

doesnt get hot enough, slow to cook

Submitted by alejandro - 5/22/2021

Very disappointed with this cooktop. We live at 8300 ft. in Colorado using natural gas. Boiling water and cooking takes longer at this altitude, but this cooktop makes it even longer. I think the gas nozzles need to be change.

Great cooktop

Submitted by Simon - 4/6/2021

Love this cooktop. The grates are great, the click stops on the controls make them precise and repeatable for cooking. Central burner delivers great heat and the other 4 are perfect too. Looks slick and modern in the kitchen.

Excellent Cooktop

Range of cooking heat settings with the different burners is awesome. Woorks like a charm and the design is slick. We had to wait a while for the delivery but it was worth it.

great appearance and fit, but...

Submitted by ktfinley - 2/6/2021

The cooktop looks wonderful and fit our needs for depth, but it does not heat as well as we expected. The middle burner is not as powerful as advertised. the burners that are supposed to provide medium btus, take forever to heat anything even at their highest setting. The simmer function is the best because it does provide a very good low heat simmer. I think that element should be at the back burner, though I guess when you have to stir something at very low heat, it makes sense to have the burner at the front. We purchased this unit because it was one of the only ones that allowed us to keep our cabinet top drawer functional. All other manufacturers products are too deep and we would have had to give up the top drawer that holds all our cooking utensils. For that reason alone, I rate it as a four instead of a three star.

BOSCH 800 Series Gas Cooktop

Submitted by Disappointed - 2/4/2021

I never write a product review, but I am hoping even person benefits from this review, I will consider the time well spent. I have all BOSCH appliances (Microwave, Oven, Dishwasher and Gas cooktop). This cooktop is used for less than 7 months and the surface scraches so...easily, it is unbelievable. It also makes "burn marks" around the burner on gas top surface. I am aftiad to use anything to remove the stains since I know anything I use will ruin the surface. Out of 5 burners, 2 take as long as 8 seconds to ignite and several tries. The customer service at BOSCH is a joke. There is always an hour hold time on the phone. A representative came and told me "it is normal to have up to 15 seconds"? Seriously?? Save your money and spend it for something better. I am pleased with the dishwasher and Oven, though. Microwave keeps condensing after every use. Which I have never seen before with even the cheapest brands.

Not what I expected

Submitted by sueforgets - 12/18/2020

I am very frustrated with this cooktop. Have only had it a few mos. & I have constant trouble lighting the burners. I do what the instructions say but once it's lit by the ignitor & I turn the dial more, the flame goes out! I try over & over--sometimes I get lucky. My husband has better luck but occasionally also has the problem. Maybe one burner that is more troublesome than the others needs to be adjusted; I hope that's all it is. Haven't called customer service yet. Also, despite the fact that these burners are much more powerful than the 32 yr. old Creda cooktop that it replaced, it takes longer to heat up since, as others have said, the grates are too high from the flames. I should have listened but this was the only cooktop I could find that would fit on my custom area with a minimum depth that wouldn't interfere with my drawers below & necessitate major modifications. The instruction manual warns about cleaning the cooktop & all components carefully. SO many cautions, each area has special requirements--this is nuts! A cooktop should not be so fragile! I'm always afraid my cleaning people will damage it, have to explain each time if different ones show up. I love that I can use my new griddle across 2 burners, however Bosch should have had 2 burners of equal power next to each other at least on one side since they do advertise a griddle to be used this way. I try to make adjustments for the differences but should not have to if it were constructed better. I don't understand the large middle burner with 2 different flame rings, instructions not really clear how to use it. The cooktop is nice looking so there's a plus.

Gas cooktop

Submitted by Court - 10/5/2020

I like this cooktop but it's a bit tough to get it lit which is why I gave 4 stars instead of 5. You have to hold it down for so long for it to light and the knobs are a bit sharp feeling. I do like the size and the way it cooks my food is perfect.

Bosch 800 Series Cooktop

Submitted by Bruce - 7/7/2020

Brand new and had to have technician replace thermocouple on 2 burners. Works great since then. Still waiting for tech support to explain what a fitting on pressure regulator is for. Having controls knobs on front rather than side takes away space from 2 front burners and can't be used for large pots or pans.

Some burners lack power

Submitted by John - 5/13/2020

Love the design of this cooktop. The center burner is very powerful. I have found that the other burners are a little under powered. I end up having to start boiling water on the center burner and moving it to another burner for cooking. One drawback of the center burner is the size of the outer ring. It is just a hair too large for most of my pots and pans so most of the heat just goes around the pan. Handles end up getting very hot if you aren't careful.

I love my Bosch cooktop

Submitted by Liza - 1/29/2020

It has been several months since my cooktop was installed. I was worried that the fact that it would run on propane would diminish the performance of the burners but I'm happy to confirm that this is not the case. I love my center burner with its double duty. I'm sorry that I did not purchase this cooktop years ago. I have nothing negative to say. I simply love every feature of this cooktop.

Great cooktop - variety of burner sizes and strengths also extremely handy. The 19,000 BTU brute center burner is as versatile as it is powerful. Very, very happy with it.
