It serves its purpose. However it's not as rigid as I would have liked. As a result the wheels leave an indentation and they don't glide as smoothly as I expected.
The mat does not stay stable on top of the carpet. I had a sales rep. assist me and never was told that it was possibly for a thin carpet. Now every minute I need to straighten it (not kidding)…Truly disappointed…
The first time this item arrived it was filthy covered in foot prints and not flat. I assumed that must be a mistake so I requested a replacement. The second one came in even worst completely covered in dirt and warped. Unless you pull out a hose (in the middle of winter) it’s nearly impossible to clean the bottom when it’s covered in dirt due to the spikes. And then spoke to customer service who claimed the next replacement would be perfect. Nope. Same thing. It’s completely unacceptable to send your customer an item covered in dirt. Is it so difficult to wrap plastic around this thing so it’s not filthy? Zero stars.
