Since I have the Upgrade pit mat...
Here is my assessment.
It rolls up nice and neat.
Nitro and shock oil and any other fluid won't hurt it.
Easy to clean...Just bust out the garden house.
Holds screws, tools, springs and other small items securely where you put them.
Me likes alot.
If you spend $100.00 they ship for free.
Plus with this code you save $5.00 for the purchase over $100.00 ( DPPAN5 )
If you spend over $150.00 you save $10.00 with this code ( DPPAN10 )
Hope that helps,
By the way they have Team Magic F8 bags in stock.
