Question: Are the sides plastic or stainless steel?
Document: The top and front are shiny chrome and the sides are stainless steel. Of all of the toasters on Amazon.com, it is probably the most visually appealing toaster that I've seen. The downside of a metal toaster is that metal conducts heat, and so you can burn yourself on the hot sides or top when the toaster is hot.
I love this toaster. It toasts beautifully! It looks beautiful! Love the shiny blue lights when it's on. I would have given it 5 stars but I didn't realize the top and front of the toaster are a highly polished, shiny finish while the sides are a brushed stainless steel. I wish the entire toaster was the brushed stainless. I'm worried the top and front are going to be easily scratched. However, I've had it for a month or two now and so far it's held up beautifully!
And it also looks very nice and fits in well with my stainless steel appliances.
We love our toaster. It has nice large slots and looks very stylish. It looks nice with our stainless steel appliances
Overall this is a good toaster. The shiny surface is VERY shiny. Too shiny for my taste. I thought it would be like a polished stainless steel but it is much shinier. It also seems slow to toast. Overall it works fine and looks fine but it isn't perfect.
The KH734D50 toaster is part of KRUPS' "Breakfast Set" line, which includes a coffee maker, an electric kettle, this toaster, and a 2 slice toaster. The entire line is made of products which are predominantly stainless steel.Like most people, what is important to me about a toaster is that it consistently toasts bread in an even manner.
The sheen on this toaster is A+++++. The movement of the buttons and slides are constructed well. Toasts evenly and to the darkness of your preference. It compliments my other stainless steel accessories well. Crumb tray is easily removed without shaking the contents loose and all over while emptying. Opted this model over the digital Cuisinart and both my family and I are elated with my choice.
In particular, it compliments any kitchen with stainless steel appliances. It is the kind of toaster where you might choose to leave it out even when you do have cabinet space for it.Feature-wise, the toaster has all the features you would expect from a "full feature" toaster, such as various settings, dual trays to clean out toast crumbs, and a "high-lift" feature to allow you to more easily remove smaller (lower) pieces of bread.
However, neither felt too hot to the touch.Overall, this is a really nice toaster, it is very appealing to look at, blends perfectly with other stainless steel appliances, and it works very well. There are less expensive options out there, so you might find something that fills your needs for less money. However, if you are looking for "high end, high quality", this toaster is it. Krups also backs it with a 2 year warranty.
I've only had this toaster a few weeks but love it. We toast something almost every day. The only thing is,  I thought it was more of a brushed nickel or stainless than a VERY shiny chrome. Not real crazy about the chrome but like the way it toasts.
