Bests & Worsts Reviews from Amazon

This thing is two pieces- one end is the hard plastic end which attaches to the second end which is the flexible hose. The hard end has an inlet and that inlet is so small that it impedes substantial airflow to your vacuum. Moreover, even small objects cannot pass through this opening and it will clog up the inlet in no time. This will cause your motors to overwork and fail prematurely. When you vacuum, it's like you're trying to vacuum with a sock stuffed in the hoses. I'm using that example so show how much less air will move through it. Moreover, you'll hear your motor scream. The inlet needs to be designed so that its opening is larger to prevent overly restrictive airflow. You are warned.
