I did a lot of researches, read a lot of other product reviews and end up purchasing this Cosmo Cooktop model COS-DIC304 to replace my old unit. So glad I did! The installation was super easy. You can see the quality of the product as soon as the box is opened. Great price, looks nice, works great, and easy to clean. Most importantly, my wife loved it and kept thanking me. Need I say more!

4.0 out of 5 stars Surprisingly good cooktop
Reviewed in the United States on November 18, 2017
This is a great range for the price. Actually better than ones costing double. We've been using it for 2 months. It cleans easily. The grates are heavy! with heat resistant rubber feet so they always set properly (flat) on the stove top and no issues setting them on counter tops with scratching. The only issue, and other have had this, one burner is hard to light. No matter what you do, it sparks fine, gas comes out but it won't light. Researching the fix. We did notice that the chromed aluminum burner ring will get dark spots when hot grease gets on it while in use. A bit of elbow grease and a good chrome polish will fix that in a couple of minutes. The variety of burner outputs is super handy. We decided on this configuration because others told us that the layout with the burner in the middle, it's hard to use the others when in use. We can put a large pot on the big burner and still use the others. And that big burner can boil stuff fast!
Yes the stainless top is thinner metal than others. Not an issue once installed. The total depth of the unit is exactly what we needed to allow for a drawer under the cooktop.
So far, so good.

Update: July 2018
The unit has held up well. We throw the grates (well carefully lift..they are beefy) and put them in the dishwasher to clean. No discoloring or rust thus far. We are having the same burner lighting issues others have experienced. The solution is counter intuitive. Set the burner to it's lowest setting while lighting and it works fine every time. The flame sensors are not as sensitive as we would like. If you don't hold the knob in the start position once lit, for 15 seconds, the flame will go out. Some where down the road, replacement of these with better quality flame sensors might fix this. It's minor in the scope of things.

Cleaning has been easy. Lift off the grates and the burner assemblies, pull the knobs and you have an easy, accessable cleaning area. We use Windex and a sponge, wipe down with warm water and a hand towel. Occasionally I will use some stainless spray cleaner and polish. After a year of use, it still looks great. Well, accept for the area we learned not to use the scrubby side of the sponge.

The unit's biggest 2 issues are: the stainless surface scratches easily and the aluminum burner rings are now black. DO NOT clean hard to get off grease or whatever, off the stainless surface with the scrubby side of your sponge. It will permanently scratch the surface. This tells me that this is not great stainless metal. The burner rings appear to be cast aluminum that is machined. Any grease that gets on them will burn in place and leave the ring spotted black. This is a bad use of materials on their part. I am going to get them power coated and that will fix the issue.

The burners all work great and the big on boils a big pot of water darn fast. I brew beer and this will take hot tap water to a boil in half the time using any of the other burners...or any other stove we have had. Monster BTU output. 5 burner cooks tops always get crowded when they are less than 36" wide. But having the big burner on NOT in the middle, makes this cook top way more useable with multipul post and pans going at once.

make sure to check if you have a natural gas tank or propane gas tank.We ran into a small problem where we had to buy a separate conversion kit for it to fix into propane gas.

1.0 out of 5 stars Awful product. Poor craftsmanship.
Reviewed in the United States on August 6, 2021
This is the worst product and company I have ever dealt with. I chose this product after a lot of research and felt like the reviews were positive, and I liked that we were supporting a smaller company in the US because my hope was that with a smaller company there would be more attention to detail with the product and it wouldn’t be so mass produce as with some of the larger companies who mass produce thousands per day.

When we installed the cooktop we realized that the grates we were given that were “brand new” already were scratched and rusted.
I contacted customer service who sent out a new set of grates. Those also arrived rusted, scratched, and missing the rubber feet that prevent scratches on the actual cooktop. It was obvious the grates have been used and returned by someone else.
I have no idea why, but I agreed to let them send out a third set of grates.
Those arrived yesterday and one was in good condition and able to be used, but the second wasn’t even for the size of cooktop that I have. They sent 2 completely different sizes and didn’t even check. Clearly, this company lacks pride in their product and service.

I would say the cooktop works OK but not as powerful as I thought with the super burner. It is also a complete pain to clean. Even with a microfiber cloth it still looks streaky.

We’re now planning to spray the grates with a high heat stove spray paint so they don’t corrode and continue to rust immediately, but we will only keep it for maybe the next 5 to 6 months and then replace. I would do it now but after a full kitchen right remodel we need a bit of a break.

Sadly, you truly get what you pay for on this product. I would give it zero stars if possible.

3.0 out of 5 stars Burners are excellent. After a few months some places on the finish is wearing/chipping off.
Reviewed in the United States on May 25, 2024
The cook top function great. There are 3 levels of output from 6 burners. The burner area of the cook top is easy to clean and does not stain. However, the printed labels are wearing off after just six months and he finish on the burner knobs is peeling/chipping off. The company sent replacement knob bevels (cheap plastic), but they will not do anything about the printed labels wearing off. They said I could buy a new top ($200+), but that would not be covered for wear either. I would avoid this product.
