I've been using that particular brand of foam saw for several years now. It's been quite reliable and it isn't nearly as expensive as a Bosch. But, and I could be wrong about this, I think the both the blades on a Bosch move, on the one pictured only one moves.
I've found that you need to be good about cleaning the blades regularly if you cut through a lot of glued foam. I am not allowed to use silicone spray at work, but in the past I've used it routinely and it really makes a lot of the cutting a good deal easier, esp. on tight radii. It's very loud; I like to use hearing protection when I have a lot of cutting to do... boss laughs at me.
(I need to buy a saw for myself and that's the one I'll probably buy).
