Question: Does this come with the pictured SQUARE elbow to attach to wall?  And how goodis water pressure?
Document: my plumber could not install bc of so many missing parts. i had to return it but bought another one, but remember YOU MUST BUY &#34;wall elbow&#34; , it doesnt come with it .. once i get another one, i'll review on its quality, hopefully there won't be any missing parts this time around
This is a very nice handheld shower but it does not include the Delta Faucet 50570 Wall Elbow Square is not included that is shown in the picture.
I love the look of the new shower we just put together! Every piece by Delta is beautiful and I can't wait to be able to use them. Unfortunately, the Vero Slide Bar Handshower is not as expected. I was really disappointed that after spending that much money, you have to spend at least another $40 depending on where you buy it, to get the elbow connection piece 50570-SS to attach the hose to the pipe.
Priced right but missing the 50570 elbow,  disappointed.Other than that it was a great product, looking forward to installing it.
At 150 dollars, this is just at the limits of "pricey" bordering ripoff. It is the least  featured shower head you'll ever find, mated to a thin bar of square tube. That said, it's awful pretty, and I like that the holder uses a push button instead of a wheel to tighten and didn't mind spending the money on it. However, to open the package and realize that the elbow isn't included is unforgivable in my book.

You can never go wrong with Delta. Quality craftsmanship. Looks great in new finished basement bathroom. Gives high end look to bathroom shower. Worth every cent.
Very well designed, well made, easilyinstalled. The shower looks beautiful, works well, and should last for a long time.
Very nice quality for the price. Not only it looks good, works very well indeed. Will definitely continue buying Delta product in the future.
The photo doesn't do this justice. It is a thing of beauty. Far better than what was expected. We were worried that we wouldn't like it because the photo showed it looking dull. It arrived and it sparkles like a jewel in polished chrome. Can't wait to install it and use it.......It's installed now and it is wonderful. The bar allows us to raise or lower the hand held wand for our grandchildren and it operates so smoothly. No harsh spraying.
Answer: yes
