One of the things you first notice about the USO 5-25x is how big the thing is... everything about it is big, or at least feels it compared to the USO 3.2-17x and other ~5 to ~25x tactical scopes (Premiers, NFs, and Leupolds are the ones I have most experience with). If you can get comfortable with that, you can move on to the rest of the scope. I never was able to get comfortable with that size, so I sold mine and moved on. That was my experience, as you requested.
