Easy rolling base
Size: Large, Color: Black
I purchased the umbrella base to enabling the ability to hold our umbrella and easy maneuver the umbrella on a paver patio. The base supported the umbrella and rolled sufficiently on the paver surface. However I did have an issue when readying the base for storage that the plastic umbrella pole support caused a black staining liquid on the pavers when it spilled on the patio

Very easy to set up and start using within minutes. Easy to move around. It holds up well with wind gusts up to 35MPH (when umbrellas are closed and the brakes are engaged).

Really nice umbrella base!

Love this base! It holds all size umbrellas. Very sturdy and the wheels are great! Has screws to hold the umbrella pole. I am so happy I bought this base!

Holds the umbrella in moderate winds.... but very difficult to roll around
Size: Large, Color: Black
Really wanted something that was mobile - and this is, but just barely. Wheels bind and get hung up on the smallest ridge or bump. It really takes two people to do it.
