Product review (4 stars): Good Value
I like this product- (4 stars)
We've been installing SS in kitchen jobs for years, and the critical reviews of this product sound like they're from folks unfamiliar with its use and installation.
This stainless steel is ferritic, probably type 430, and so it is somewhat magnetic.
We used to only use type 304 (also known as 18-8, reflecting its content of 18% chromium and 8% nickel) which is non-magnetic, but as manufacturers have gone to 430 for their kitchen appliances there seems no reason not to be using the lower priced type 430.
We install back splashes with construction adhesive, applied with a caulk gun directly to the sheet rock on the wall.
Would prefer no mounting holes, but not a problem to use them too; belt and suspenders.
The SS is then held up by a nail or two temporarily placed in the sheet rock below the SS panel, and is pressed tightly against the wall by various sticks clamping it into the adhesive overnight; next day both clamping and nails are removed.
Like others mentioned, in spite of the seemingly great packaging, our back splash arrived with two bent corners; this is my only reason for not loving it. (5 stars)
Simple to straighten the corners back out, but would have been nice not to have to do that. (PlumStruck- are you listening?  Improve your packaging!)
Pull off the protective plastic film before installation, (yes, the brushed side is the side you want to be seeing, not the polished) removing the plastic after the install will sorely test your patience.
Good value- recommended!
