SATV Full metal doors

Im looking for some doors for the rzr and I came across the satv full metal doors but I can’t find much information or reviews on them. Does anyone have any experience with them? Also I don’t understand the benefits or drawbacks from a suicide door vs a regular opening door. These particular doors open like a regular car door but I don’t know if thats good or bad. Most that I looked at are suicide doors. Can anyone elaborate on that?
