I use these to hold my extension chords in my work truck. I'm very happy with them, easy to use, super convenient, very strong.
So I use these on the back of my wheelchair to hole heavy shopping bags. I can have cans gallon jugs whatever I'm shopping for and these hooks are like extra hands. Great for back of chairs or the seat of your car can hold a lot of weight
Out of the box you can feel they are sturdy.I have one facing the rear and one facing the front to hang my hats.
Sturdy held up good
I used to have the plastic hooks but after about 2 years they got brittle and cracked from sitting in a hot car most summers. These ones being metal don't show any signs of bending or giving to slight weight. I use one hook to hold up a gym bag that has straps, belts, headphones and a couple other things and probably weighs about 5 lb. The other one I use for groceries which I usually hang several bags from probably a cumulating to about 20 lb. Overall it's just a metal hook that you hook to your headrest but if that's all you're looking for then it does the job.
