Budget Baddie...
Color: Tan, Size: 9 Foot
This is a quality/durable self driven (me) beast of an umbrella replacement...It has good color and we chose the Tan 9ft. Easy usage for its weight class all while being budget friendly... atmospheric presence of richness & sturdiness, and very easy to open and close to adjust to this unit's comforts. I haven't put this umbrella out for the season as of yet... because the snow is still present on the grounds of New England! "WE WINN"

Beautiful and works great.
Color: Navy, Size: 10 Foot, Color: Navy, Size: 10 Foot
I decided to try this because my old umbrella had seen better days and it was time to replace it.
I am very pleased with the quality and the ease of assembly with this umbrella.
It’s very sturdy and I like the quality of the fabric and the metal. It’s very easy to open and close and it makes my patio look great.
It gives me the perfect amount of shade and the fabric thickness is perfect at keeping the harsh sunbeams from getting through.
I also think the price is great for what you get.
I would definitely recommend this umbrella because it’s made well and works well. It’s also very easy to clean. I just use my garden hose and spray it down and let it air dry.
It also fit perfectly in the stand I already had and it works great. I am very happy I got to try this out.

Great replacement patio table umbrella.
Color: Tan, Size: 10 Foot
After a windstorm destroyed my old umbrella on our patio set, I was looking for a new one that wouldn't break the bank but also held up to the direct sun of the summer months.
This umbrella did not disappoint! The material part of the umbrella top seems like it is nice and thick and the stitching is overlapped in the corners which should provide a lot of strength for the windy days. I really like the neutral colors of the fabric, as that will go well with the rest of my outdoor furniture.
The medal pole portion is perfectly straight and the pivot point connection seems nice and tight. I would think that this umbrella will stand the test of time.
No assembly needed, just pull it out of the box and extend the fabric.

Incorrect height shown in listing image.
Color: Tan, Size: 9 Foot
I purchased these for their tall height to go in the ground, but they are too short and I hit my head on them. The height shown in Amazon's pictures does not match the actual height for the 9- and 10-foot umbrella. The heights are something more like 90-95 inches rather than the 108 and 120 inches indicated. The 9- and 10-foot umbrella description seems to refer to the diameter of the umbrella instead. I have returned them, but Amazon has not yet corrected the listing.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty.
The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home.
Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down.
They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price.
If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.
