Some silly questions about the Powerblock dumbbells

I'm thinking about purchasing the powerblock dumbbells I think the sport 24 and just have some questions (some silly my apologies in advance)

1. I have pretty small hands and even holding neoprene dumbbells is kind of awkward would I experience that with the powerblock as well?

2. I've read some reviews saying when it comes to dumbbell curls apparently the dumbbells don't curl all the way (does this makes sense?)

3. How sturdy is it? I'm scared the weights may fall on my face or head or toes.

4. Apparently it's noisy is that true?

Thank you for bearing with my questions
