Roll out flooring G-floor (Costco) anybody use ?

Wondering if anyones used the "rolls" of floor covering Costco or other places sell ? , Looks pretty good just can't see anything other than parking on it.
Might be good for where I'll store the lawn mower and mini bikes etc.

I don't see why it's so expensive...

I'll leave my floor bare - before I'll pay that price for a rubber mat

I've seen these mats installed or rather rolled out in garages and from my experience they will eventually do more harm than good. Think of when you place a mat on your front door step. Even on a sunny day, when you lift it, there is moister trapped underneath. This roll out mat will do the same, trap moister, specifically near the garage door where its exposed to the elements. This will eventually detiriorate you concrete. For the price, just pony up a little more for a modular floor. Most, even the solid ones are designed to allow air to flow underneath.

If you need a mat rather than a floor, then they are fine. But all they are is really an oversized expensive mat.
