Question: Is the end threaded?
Document: Good sturdy pole, but Amazon put it in a box that was 10 inches too short. They cut a hole in the box and stuck out the threaded plastic end that got beat up pretty bad in the journey. The UPS guy said he made a note of the packaging in his shipping order because the damage wasn't his fault. He couldn't believe it. Neither could I.  I expected more out of Amazon...
Needed something to help me clean our windows. We have windows in our entry way that go up to about 16-17 feet. Attached a squeegee to the end of this and it cleans like a champ. Good price, seems to have good build quality and it feels sturdy in your hands, even when telescoped all the way out.
exactly what I expected with quality but not with reach. I underestimated the reach and distance to my windows so I will need to order a much longer pole. Very sturdy and push button release is a breeze.
Well balanced, sturdy, good value. I was unsure what size pole to purchase, and I made the right choice. Any shorter, and I wouldn't be able to reach. I need a step stool to reach some of the high windows, but any longer, and it would be cumbersome, and difficult to use. I'm sure I'll find many uses!
Very happy, my boyfriend was very pleased with it. He's a window cleaner and was shocked I got it for him for Christmas.
This pole is useless. You open it up to reach a high window and it slides back closed,  There is no way to make it stay open, or at least none I can find.
This is a well constructed, inexpensive product that does exactly what is promised. i have used it for a couple of months now and could not be more pleased.
This extension pole does exactly what it says it will do,  Cleaned all the windows on the inside and outside of my house in less than 45 minutes using the 6500 kit and the extension pole along with the Ettore cleaning solution. If you are using the 6500 cleaning kit, make sure the release button is inserted so the button is on the un-padded side of the tool handle. Otherwise it is too difficult to depress the button fully to release the tool from the pole. Great system.
The pole came , and is as advertised. I need it to reach two cathedral-type windows inside the house that I can't reach any othrway. The only r eason I didn't give it five stars is that I can't risk dripping down to the first floor.
The only reason I gave this 4 stars is because it wants to stick in the squeegee and scrubber handles.Other than that it works great and doesn't bend or wobble even if extended all the way. Can easily adjust to whatever length needed. I have the professional window cleaning kit I use it.
Answer: yes
