I seldom if ever adjusted the length of my telescoping wand from ProTeam. So when the coupler (adjusting piece) on the ProTeam wand broke I decided to look for alternatives and this was the perfect solution! Less expensive than the original wand and zero parts to break or fail! I bought from Cen-Tec Systems because I have been using their Sidewinder attachment for a couple years now. If you haven't tried one of those you owe it to yourself to. A Sidewinder combined with a straight wand (like the one being reviewed here) and a backpack vacuum and you will wonder how you ever got by without them before. What a time saver and so much less energy required while vacuuming, not to mention not getting a sore back!
