I have zero complaints about my Nutribullet Pro 1000. I just add my ingredients, twist the cup and let it do its job. In just one minute I have a perfect smoothie. 
I haven't tried it with fresh fruit or ice yet. So I can't say how well it performs on that, but I cannot imagine it would be much different. 
My husband and kids (14 & 18 yo) all want to use it. It's fool proof, so I gave a quick tutorial, & now they can make their own. Best Mother's Day gift!
