They are made of a hard plastic and are hard to open and close.

4 stars because they still feel like they are made out of cheap plastic and although I am under the limit, I still feel like it is going to break sometimes.

This is a VERY cheap plastic product

The outer housing is made of some type of very hard plastic like material

Nice solid ratchet feel and good solid thick molded plastic

I expect these light hanger will outlast the cheaper plastic models.

Some of the others have hard plastic handles with seams that irritate your hand

No cheap parts or plastic pulley here

Other then that it worked as

My hands didn't cramp up as much as they did with a plain Aluminum hook

I have used it to clip on the side of my mirror for better lighting for makeup application, onto my car visor mirror (same reason) as well as to light up my purse to find my phone, etc

I use the Niteize S-Biner #5 clips to secure the emitter and the hangers to the load bearing 3/8th(?

She had tried the "s-curve" shaped ones and it cramped her hands even more

I am using these hangers to support a heavy 4', t-5 light fixture

Nice I like it has different levels of light.
