I have carpa tunnel specifically around hand tools from a work injury using a hammer. This extension pole is sturdy and well-made but far too heavy for my limited grip strength. After a single coat on the ceiling I could barely hold it with the added weight of the roller. The thread also unwound itself off the roller a few times. Definitely cost effective and good quality but not good if you have low upper body strength or manage rsi and carpa tunnel. If that sounds like you too, head to your hardware store and find something lighter and more manoeuvrable.
