Off gassing, but not surprised considering what it's made of. Works well, but only as they suggest...on smooth surface and when using the strips vertically, not horizontal. I mounted a very large surge strip on my LR side table and the first time I did horizontal strips. It fell down two days later. Carefully and slowly removed and redid them vertically and a year later is still holding strong. If you're very sensitive to smells, you could try 3M Red Heavy Duty mounting strips first, they work well too.
