Question: Is there a button that makes the umbrella open or do you have to open it manually?
Document: This is a big umbrella. The handle length makes it uncomfortable for walking about with it though. I guess if you're a doorman, the extra length is helpful. Open, it's a little long, and somewhat unbalanced. Closed, and walking about with it 'like a cane' isn't much fun. It's six or eight inches too long for that.It will be interesting to see how this lasts. The handle is wood, and the varnish is colored, and scratches easily (noticeably).
This isn't a problem, but it makes the umbrella thicker overall and so slightly heavier and more bulky. (2) The wood on the handle could be nicer. It looks like it will chip over time and it does not have a thick or strong lacquer. Still, I think it's a nice touch that it has wood at all.
Excellent size, strength, and quality. The size makes mevery popular on rainy days. The quallity of workemanship make this a very attractive product.
Five star rating due to it's accurate description. Have used this in winds gusting to 45+ miles per hour and truly this umbrella had no problems. Fiberglass shaft means lightning strikes are unlikely and also makes for lightweight strength over metal umbrellas. Extra large diameter makes for comfortable sharing for two people and almost guarantees that your feet will stay dry. This exceeded my expectations. Highly recommend for couples that enjoy walks, rain or shine.
I once had a huge umbrella like this but the one got damaged. This is a great replacement. The only minor problem is that I thought it would be a push-button model that opens itself.
I'd give this umbrella a (0) rating if I could. From the firsttime I used it, the umbrella wouldn't catch onto the clasp tokeep the umbrella open. Of course, this would only happen in the rain. I'd send it back to them, but I threw the thing away. That's where it belongs. Don't waste your money.
Not sure why this happened. It's rarely used. Metal at top broke so impossible for it to stay open. Wish I could exchange it.
we've had some big time rain recently and got tired of fighting the umbrella and holding on to the dog at the same time. The doorman umbrella has been perfect. I don't have to fight the umbrella when the wind comes up & big enough that I don't get drenched on the long walks. much recommended. This is the second one I've owned ( my dad stole my first one for his own!). well constructed and easy to open and close.
My wife is a school teacher and escorts pre-schoolers from the school bus to the school door each day. This umbrella lasted exactly TWO rainy days before the clasp near the top of the umbrella that holds it in the open position collapsed into the umbrella stick, making the umbrella useless. It no longer stays in the open position. Lesson learned? .....  Go to some golf shop and buy a nice umbrella from them, I guess.
Wow!! This is a sturdy umbrella that will last for years!! It is attractive and classy in every way! Easy to open, easy to close, withstands high winds and heavy rain - and is big enough to protect you from high winds/heavy rain! My daughter and I were caught in a complete downpour with winds whipping from seemingly everywhere at once - some rain was sheeting sideways. I was worried because I had parked halfway across the parking lot and had a meeting to go to.
Answer: yes
