Very thin plastic, but hey, it didn't cost much either.

Super thin plastic. Need to be careful if its full of liquid as the walls will bend when you pick it up. On the other hand, it's very lightweight.

It's a nice looking product, however it feels like plastic. Very light and has no real weight to it.
No problems with delivery, however I'm not likely to purchase this item again.

Did not like it do to it being very thin plastic which in turn it will probably not last very long.

Light weight plastic with a low profile wedge. I had to take too much time, place it carefully and hope no one breathes. Not worth purchasing.

This..I didn't have high hopes for, especially when I got it and felt how light weight it is. The plastic seems cheap, however it has last thru my grandkids dragging it around the yard for summer fun. Ive had it a few months and it still works great.

These are thin and flimsy plastic.  I would rather pay a little more and get the thicker kinds.

It is plastic and a bit light (it doesn't cost a lot so this is not a criticism) but it does what it's designed to do and it does it good.

Kind of light weight and cheaply made but for the price, it is hard to gripe.

Must mirror other reviews here in that item is made of light weight flexible plastic. Might be a good idea for those less than flat shooting benches, but may want to have a sandbag to set on it to help keep rest stationary. Assembly was easy and fit and finish seems good aside from easily flexed material and needing weight.

These glasses are so lightweight that they could pass for plastic.  That makes them seem cheap.  I'm returning these for a set with some substance.

Very light weight plastic, but programmed easily and haven't failed (We have had them about 2 months)

It is very thin and very light.  Think Soda can, cut in half with a lid.  But hey it was cheap.
