Attractive and seems like it will hold up
Size: 6.5x10ft, Color: Blue-Green Stripe
Seems sturdy enough. Tilt button is difficult to retract to straight, but maybe just my finger strength, or it will loosen up with time. The color of one of the stripes is off from the photo. I was hoping it was turquoise as shown in picture, but is actually a much deeper blue. Doesn't coordinate with my other patio colors like I hoped it would, but it will do.
