Plant Training Clips, Questions & Recommendations

[Newty]

I've never used training clips before, just wire. I'm wanting to start using them but have a few questions.
I posted pics below of the ones I've seen for sale.

Are the different colors, different sizes?
Are the adjustable clips any good?

Seems like a common complaint in the reviews is that they are small and the plants out grow them quick, is there bigger ones available or what do other members recommend?
Thanks!

Last pic dont bother! I got a million pack and I feel like they are a little too small. The first pic is what I wish I had gone with, or something very very similar!
