When my mat goes in the maker it just slides itself to make it work without any troubles. With the wheels, it moves easier and the vacuum can get under it. Now when i need the occasional tool, it rolls out without a fuss.

I put 4 wheels on it and as soon as i turned it over and the weight on wheels 2 wheels broke off.

Great value and sturdy. Great buy cheaper than ikea or homedepot.

There is no way these can support the stated max load without flattening. Out of the 24 one was doa but 23 are ok. Quality is questionable.
