Basset M1a scope mount.?

Does anyone have anything bad to say about these mounts?

The single point of contact raises my eyebrow a bit. The 45 degree rails is odd, but not much of a concern for me. They also are ridiculously easy to install.

I understand they are aluminum. I was anti aluminum for awhile, but for the amount of money I want to spend, I don't think I'll be getting steel. Besides, this is for a recreational range rifle. I won't be using this for hunting, competition, or in the field in any way.

In fact, I'll probably still shoot my gun with iron sights most of the time, I just want the option of mounting a scope if my buddies want to have a friendly competition to see who's buying lunch.

The Sadlak and Springfield armory mounts are right about the same price. But I still have people recommending the Basset to me regardless. I'm not looking to invest too much into this, and $150 is about a reasonable enough price tag. I won't even be buying a new scope, I'm just going to use one of my old hunting scopes in my random gear drawer.

Any reason why I shouldn't go with this thing?
