Arrived with no instructions so looked up online including the listing's embedded link. Problem is that unit sent was a different version than the ones pictured with completely different parts. If you take time to think it out and only finger tighten until you've got it all together,it is a good unit. Missed out on a couple plastic endcaps because I thought they were "packaging" like similar pieces but were needed to keep a tight fit on handle sub-assembly. for those who are handy and have plenty of time!
