Excellent - meets our needs perfectly
Your review: We transport delicate equiment between 2 buildings, approximately 50 feet across a rough asphalt surface. We had been using carts with standard castors - the transit was extremely rough and tried to vibrate equipment right off the cart.
The pneumatic castors on this cart make the transit extremely smooth - I could not believe the difference. I don't think I really needed to buy the ledges that I purchased to keep equipment from vibrating off the cart as there is no vibration.
As for the cart itself, we have appoximately 60 - 70 wire shelving carts in a variety of sizes and configurations, both mobile and fixed. These are very good, reliable, and economical products in my opinion.
