Which device do you advice?

Hi guys,
Jelqing is much more easy then stretching for me but I want lenght and I don't have enough time to do stretching exercises. Can that stretching devices help me? Which one do you advice? And are these devices effective as much as the stretching exercises? Thanks.

I used the jez extender for 3 months and it was nothing but trouble,gained no length from it.
