I have not used it yet, but I have ordered the cooktop. I chose NOT to order the trim, the salesmen indicated he thought it was one more place for crumbs to get stuck both between the cooktop and the trim and the counter and the trim. The only upside I could rationalize is that it would protect the corners of the glass. As I am already trying to minimize mixing variations of stainless and nickel in the other elements of my design, I opted to go with the non-trimed NITP666UC. I have posted several times on the forum asking for how people like the cooktop, but have not gotten anyone to share their experience. Hopefully we will hear from others with this thread.

I am also in the process of ordering my Bosch induction cooktop. I like the look without the trim, but my salesman said that the trim helps protect the edges from chips that may occur when using heavy pots or if something heavy is banged into the edge. I am also concerned about the ease of cleaning with the edge. Any feedback from induction
cooktop users would be helpful.

My salesperson also said the trim protects the glass. Her suggestion was that if we went with the trimless she would suggest installing it flush with the countertop. I read about that and while it is a nice, clean look it makes it more difficult to service the unit.

I like the trimless look but will probably get one with trim for those reasons. All I ever read is how easy these are to clean.

I just ordered placed my order on Saturday.

The salesman highly recommended the un-trimmed unit -- he said the trim would scratch too easily and look dated in a short period of time.

One more thing to think about - - if you install flush with the counter top and need to replace it down the road (hopefully not) you will more than likely need to replace your counter also. It's a good lesson learned that he personally experienced. He had a Wolf electric cooktop unit that died (new units were a different size) and it was an expensive mistake.

I hope this helps.

I'm going to get the untrimmed unit just because I prefer a less-is-more look.

About chipping: I'm not worried about it. I've had a gas-on-glass cooktop with untrimmed edges for 20y and never had a problem. Besides normal pot moving and shaking, it has also had more than one thing smashed on it (hamfisting stuff out of upper cabs) and nary a scratch or chip on it.

Personally, I think they offer SS edging on these things for people who are hung up on 'all SS appliances' kitchens.

Just for some perspective, my induction unit came with trim. Since I also have gas, it looks better with it, so both are SS outside and black in the center. In general, I don't care for stainless and otherwise would have chosen without.

I'm sure this differs by maker, but the only place I've had an issue with crumbs is where the handmade tile counter is a bit uneven under the edge of the trim, and there's actually a gap. It's not a big deal, but I try to route crumbs away from there so I don't have to bother fishing for them. They don't get caught in the surface edge at all. Not even fine cornmeal.

No scratches on the trim either.

If you want to see trim, get trim. If you don't, don't. It would perhaps make decision making easier if there were an obvious functional difference, but there really isn't.

I have the Bosch 500, bought about 18 months ago, with stainless trim on front and back, but not the sides. I actually bought this model despite the trim, since I thought I preferred the plainer look without trim. Well, it turns out that the stainless steel trim actually prevents crumbs from getting stuck in the front and back areas, since it's slightly beveled. Crumbs, flour, etc. just falls off the edge onto the counter. On the sides, where there's no trim, I have had to take a toothbrush once or twice to clean out the very slight separation between the glass of the unit and the counter. It's not a big deal, but I thought it would help you to know about it.

By the way, I love the Bosch induction cooktop.

zachin, I have the same unit, bought around the same time, same advice, and I love it too!
