I am very happy with this pointer. It is all metal construction. The pointer has an adjustable aperture so you can have a thick or thin line. And it has the added bonus of using regular AAA batteries.
The are only two downsides and they are both minor. The first is it doesn't come with batteries. The second it took about 3 weeks for it to be delivered with the free shipping option. It is shipped from China and it takes some time.
I use it for tabletop miniature gaming to determine line of sight and it works great.
