They feel light and not very durable, but they are made of good plastic.

The dry-wall screw mounts that hold the guitar's weight are made of a very cheap plastic

The first one failed when the mounting screw heads sheared through the cheap plastic body of the hanger

Will update review as to durability as they were hollow plastic on wall mount which would make me nervous if my instruments were highly expensive

It's hard plastic with rubber sleeves

Good hanger, the plastic is on the flimsy side but for the price its better than I expected.

Make sure you use the right screws and the right plastic anchors so it hold in place really well.

You can't really bend these unless you use tools to permanently do this without breaking the plastic

Cheap plastic/hardware

They worked for what I needed and for the price they are awesome but they are made out of cheap plastic.

The plastic is not too hard or too light: it does not seem as though it would easily crack or go brittle with time

Don't over tighten the screws as you can crack or damage the plastic.

Good hangers for the price, but throw away the cheap plastic anchors that come with this and go down to Lowe's to get a couple packs of metal self drilling drywall

Cheap plastic

It looks like the set I got weren't able to support the heads shape as they broke off the physical mounted part

No frills guitar hanger that works exactly as I expected it to.

The bigger body dreadnought acoustics tend to lean back a

Good quality & they work exactly as we intended, and have been holding our guitars up on the wall for many months

Hangers work nicely, but the wall anchors that come with them are cheaply made and broke as soon as we tried installing them
